Ah, some more make the list.  OK, I obviously was too severe in my
comment ;-)

Let's just say that most mid priced SLR cameras, are not likely to come
with 100% viewfinders, and that more likely, cameras which do have them,
are top of the line models...


The feature costs $$, so only the "creme of the crop" gets that

I agree with you that the real reason behind the mid and lower end
cameras not being 100% was due to cost of trying to calibrate accurate
viewfinders to film frame.  The 92-86% numbers (I've even read of 90% or
89%) do allow for quite a "fudge factor" in the design.

Thanks to all for correcting my statement.  It appears the 100% club is 
larger than memory served me.  It is still the top of the line products, 
principally, but not as exclusive as I stated, for sure.

For sake of interest, Popular Photo rated their F3 test camera at 98.8%

as one can expect.

That's incredible.  I thought only HP was asleep at the switch
on this, with their HP Photosmart and S-20, both of which will destroy 
your sixth frame if you use a full 6 frame film strip.  HP finally made 
the software limit intake to 4 or 5 neg strips to "resolve" the problem.

Re: filmscanners: LS4000 slide removed from mount

2001-06-04 Thread Arthur Entlich

Is it that big a difference?  We're speaking of the light angle 
differences which can allow for an exposed area due to the gap between 
the internal frame mask within the camera and the film plane... so, 
that's based upon how far the guide tracks stand out from the frame 
surface.  On the Nikon I just looked at, the guide rails actually make 
up the top and bottom edge of the film frame mask, so the difference 
there is zero, the short edges do have a small gap, I'm guessing less 
than 1/32nd of an inch, assuming the film lies perfectly flat.

How much difference in frame length could that make?

These prices are getting downright silly!

Since the issue of CD-RW units came up, I'm wondering if anyone has 
happened upon any info in regard to the life span of the write laser (or 
other potentially "weak components" in these units.

A local computer chain here regularly supplies the info that these units 
are lucky to last a couple hundred writes.  Of course, that's just 
before they try to sell you their extended warranty, so I take this with 
a huge grain of salt.  I was wondering if anyone has read any documented 
info on the real life span of CD-RW drives, or if people have personal 
experience as a basis.

I haven't burned a huge amount, so I'm a bad example (about 100-150 at 
this point, including CDRW disks).

Of course at $89 US, who cares, but mine cost me nearly $400 CAN for a 
8x drive, and I'd like to think it will at least amortize out at $1 a 
disk for the burning part.

Re: filmscanners: VueScan Question

2001-06-04 Thread Arthur Entlich

I don't mean to question your authority on this, since I don't own a 
2740 and you probably have worked with one, however, I am trying to 
understand the mechanism of this situation.

I understand that dICE works by doing a comparison of the infrared image 
and the "visible" image and does some sort of subtractive process, to 
assume that stuff that is on the one and not the other is likely dust, 
dirt, fingerprints, scratches, etc.

I also understand that the concept of multipass is to "average out" the 
random noise a CCD produces in the visible spectrum, by basically 
assuming any pixel which alters value through a number of scans is 
likely an artifact of noise rather than "real" data.

What I'm not clear on is this... Does the infrared scan tend to have 
similar amounts af shadow noise during its data acquisition?  In other 
words, is it really necessary to do 4 or 8 or 16 infrared scans of an 
image to get a more accurate infrared scan of the image?  If so, 
wouldn't that mean that dICE actually adds a certain amount of random 
noise (or random artifacting) to the scan when doing a since pass scan. 
  After all, if the visible light scan makes an image and during that, 
the shadow area data contains a certain amount of erronious random 
"noise" artifacting, and then the dICE infrared scan does the same 
thing, wouldn't that introduce a second level of errors, since the dICE 
scan would have different random pixel data (noise) than that of the 
visible light scan, and when the subtraction formula occurs, some data 
would either be subtracted that should not have been, or not subtracted 
that should have been?

Again, I'm guessing, but I would be surprised that the infrared light 
scan would have very much noise artifacting in it.  I'm therefore also 
guessing that taking one infrared scan and then simply using it as the 
subtractive model for all the multi-visible light scans would make 
little difference in the final result.

Ed, if you have access to an Acer 2740 and can write you software to do 
this (take one infrared scan, and then average all the visible light 
scans and then do the subtractive process once) you will find almost no 
difference in the final result, and probably no meaningful difference.

Coming from this with no way of documenting it, but using "gut science" 
;-) only, I very interested if such a test could be carried out.

This would tremendously help any 2740 owners when doing multi-scans with 
dICE.

Re: filmscanners: VueScan Question

2001-06-05 Thread Arthur Entlich

Hi Ed,

Again, not to be argumentative, but, I do understand it is the same CCD.

That isn't the issue.  We know that, for instance, typically the blue
scan is noisier than the green or red, right?

I have no idea what type of response the infrared sensitivity of the CCD
is, but I'm (guessing) that the infrared scan looks nothing like the
visible light spectrum scan, and isn't influences at all in the same way
to shadow density of the visible light scan.

Have you tried my suggestion just to see if it makes any visible
difference? (perhaps just doing a compare of the IR scans in Photoshop
might give a clue).

Can you perhaps post an example of what the infrared scan looks like of
a typical image?

If you are stating that the CCD has the same response to IR light as to
visible light, then I am guessing the dICE system is adding a certain
amount of random noise to the scan, in fact, it is, in effect doubling
it in a one scan situation, since each scan introduces a different set
of noise and the they are subtracted from one another.

And again, the question I asked last time begs to be answered:

If the visible light scan introduces erroneous random "noise"
artifacting in the shadow area data, and then the dICE infrared scan
does the same thing, (capturing different noise and random errors)
wouldn't that introduce a second level of errors, since the dICE scan
would have different random pixel data (noise) than that of the visible
light scan, and when the subtraction formula occurs, some data would
either be subtracted that should not have been, or not subtracted that
should have been?

I think it may be time to ask our friend from ASF for some comments
about how CCD's respond to IR, etc.

Speaking of the RFS-3600, Kodak is again lowering prices on it.  They

Well, it is pretty obvious they have been dumping them on the market. 
The prices here in Canada are close to zero with rebates.  And that's 
with a $.21 levy/disk on them, being paid to "top 40" musicians and 
record companies for "loss of revenue" due to CD-Rs being used to 
'illegally' record CDs.

I was wondering about why the problem was just CD-RW, but you have now

Of course, if everyone panics and buys up the store stock on hand, the

I think there are more APS cameras on the market made by the major

Nikon, Pentax, etc, all have APS models, and usually several to choose from.

But you are absolutely correct that Kodak has a business plan involving

However, the idea of giving away 100 rolls of film to sell a scanner is 
a new one for them.  Of course, they keep their lab clients happy, by

I realize that CD-Rs are not directly a film scanner issue, but I'm sure
we all are using them to store oure images at this point, so I;d like to
make a few other comments about the matter of CD-R quality.

Some of us rely upon these disks to store our very precious data, some
of which is literally unreplacable.  We use them to back up our
computers, and to store our images, among other things.  I think we all
know that they don't last forever, and we also know that some storage
method or media will come along and ecilpse the CD format over the next
10-20 years, if not sooner.

The comment about the small companies making CD-Rs and them going for
$.10 each is important to consider. The number of CD-R manufacturers is
far greater than the brands you see on the shelves.  Why?  Because many
of those "branded" products are not made by the company on the label at
all.  The "brand" companies simply contract companies to produce disks
which eitehr meet their specificatiions, or at least have their name and
logo on them.  Whne someone says "I buy 'Maxmembatim' disks and they are
good/bad, even taking the issue of the burner, software and computer
configuration they use, usually teh brand name is relatively
meaningless.  The reason is because these companies by from whomever can
meet their purchasing requirements at the time.

I have in front of me 4 "brand name" disks whcih all have the same brand
name on them.  Every one of them is made with a different dye type and
different reflective surface, and when I go into them with a little
utioity that reads the name of the manufacturer, not one of them says it
was made by the company whose name is on the disk and packaging, in fact
all four are made by different companies.

TWO stories, one short one long:

I bought a 50 spindle of disks.  I'll even mention the name since they
obviously have no pride as a company anyway. PINE Technology, sold by
Samtack.  It was one of my first CD-R purchases, and at the time disks
were expensive, so I tried a basically unbranded product.  The disks
didn't even have a label on the non-recordable side, so one had to look
carefully at both sides to know how to place them in the CD-R burner. 
The dye was almost clear, and the disks were silver.

These were the first disks I burned, and of the 50, 12 failed.  I 
throught the problem was either my software or my nice (and costly) 
Plextor drive.  It wasn't until I spend some time with Plextor's chief 
engineer that we were able to determine, via the error codes, that all 
the problems were media related.

Those disks came with a one year warranty, so I emailed the company and 
requested a refund on the 12 disks (that's nearly a 25% failure rate, 
and proved a big waste of my time to have to redo all those disks). 
They informed me that they didn't refund money, but would ship me 
replacement disks.  And they did, by Fed-X no less.  They asked me for 
the bad disks back, which I offered to ship them at their expense.  Then 
they lost interest.  The interesting part is the disks they sent me as 
warranty replacements.  They were a different product completely, 
claiming "Ultra Speed 12X" on the label.  They sent me 15 disks.  Of 
them, 3 had visible defects in the reflective coating (I'm taking 
numerous holes varying from pin price sized to paperclip wire diameter).
So that's a 20% reject rate before even bruning any).  When I emailed 
the guy asking if he thought that was an acceptable rate of visible 
defects, and asking if the company even had a QC system... he ignored me.

These disks are sold in Canada under the PINE (and other brands) at 
Radio Shack and Staples, and I wouldn't go near them again.





The LON story: (Yes, the one above was the short one ;-))


I am, this very day, involved in a disagreement with a major CD-R
"brand", which has been going on for over one month of calls, faxes,
emails, etc. regarding the fact that I bought these disks (in early 2000
-- I have about 500 stockpiled) and when I bought them, I did so becaus
ethey showed a gold disk on the box, and they indicated a "Lifetime
Warranty" on outer packaging as well.  It was only recently that I broke
open the master pack of one and to my surprise, the inner jewel case
info stated that the disk had a one year warranty from date of purchase
(in other words, it had already passed).  However, the Jewel case image
also showed a gold disk.  Then I opened one up.  Turns out iyts a silver

This is just plain silly.  I always thought a PCI card was a PCI card,

OK, the first question is:  Is anyone on this list using an Acer 2720 or

(sorry, I'm sure it isn't very funny for the people of Nepal, but it is

E= Eat comfort food until you are sick to your stomach

N= Never give up

I usually wear down my opponent until they are either babbling

These techniques are particularly effective if you don't mind looking

Lastly, I will remind anyone who has been on this (or was it the 
scan@leben?) group for a year or more, that I had a long drawn out 
debate with Austin Franklin about the problematic nature of SCSI 
implementation, due to a mixture of the many versions, the dozens of 
cables and adapters, the different protocols, and the general lack of 
industry standards.

I have four SCSI adapters in 2 different computers, and as much as I 
like what they do (and when they work, they work well) configuring them

I realize that CD-Rs are not directly a film scanner issue, but I'm sure
we all are using them to store our images at this point, so I'd like to
make a few other comments about the matter of CD-R quality.

Some of us rely upon these disks to store our very precious data, some
of which is literally irreplaceable.  We use them to back up our
computers, and to store our images, among other things.  I think we all
know that they don't last forever, and we also know that some storage
method or media will come along and eclipse the CD format over the next
10-20 years, if not sooner.

The comment about the small companies making CD-Rs and them going for
$.10 each is important to consider. The number of CD-R manufacturers is
far greater than the brands you see on the shelves.  Why?  Because many
of those "branded" products are not made by the company on the label at
all.  The "brand" companies simply contract companies to produce disks
which either meet their specifications, or at least have their name and
logo on them.  When someone says "I buy 'Maxmembatim' disks and they are
good/bad, even when taking the issue of the burner, software and 
computer configuration they use out of the equation, usually the brand 
name is relatively meaningless.  The reason is because these companies 
buy from whomever can meet their purchasing requirements at the time.

I have in front of me 4 "brand name" disks which all have the same brand
name on them.  Every one of them is made with a different dye type and
different reflective surface, and when I go into them with a little
utility called CDR Identifier -downloadable freeware at:

www.gum.de/it/download/english.htm

that reads the name of the manufacturer, not one of them says it
was made by the company whose name is on the disk and packaging, in fact
all four are made by different companies.

TWO stories, one short one long:

I bought a 50 spindle of disks.  I'll even mention the name on the 
outside label since they obviously have no pride as a company anyway. 
PINE Technology, sold by Samtack.  It was one of my first CD-R 
purchases, and at the time disks were expensive, so I tried a basically 
unbranded product.  The disks didn't even have a label on the 
non-recordable side, so one had to look carefully at both sides to know 
how to place them in the CD-R burner.  The dye was almost clear, and the 
disks were silver.

These were the first disks I burned, and of the 50, 12 failed.  I
thought the problem was either my software or my nice (and costly)
Plextor drive.  It wasn't until I spend some time with Plextor's chief
engineer that we were able to determine, via the error codes, that all
the problems were media related.

Those disks came with a one year warranty, so I emailed the company and
requested a refund on the 12 disks (that's nearly a 25% failure rate,
and proved a big waste of my time to have to redo all those disks).
They informed me that they didn't refund money, but would ship me
replacement disks.  And they did, by Fed-X no less.  They asked me for
the bad disks back, which I offered to ship them at their expense.  Then
they lost interest.  The interesting part is the disks they sent me as
warranty replacements.  They were a different product completely,
claiming "Ultra Speed 12X" on the label.  They sent me 15 disks.  Of
them, 3 had visible defects in the reflective coating (I'm taking
numerous holes varying from pin prick sized to paperclip wire diameter).
So that's a 20% reject rate before even burning any).  When I emailed
the guy asking if he thought that was an acceptable rate of visible
defects, and asking if the company even had a QC system... he ignored me.

These disks are sold in Canada under the PINE (and other brands) at
Radio Shack and Staples, and I wouldn't go near them again.


The LON story: (Yes, the one above was the short one ;-))

I am, this very day, involved in a disagreement with a major CD-R
"brand", which has been going on for over one month of calls, faxes,
emails, etc. regarding the fact that when I bought these disks (in early 
2000 -- I have about 500 stockpiled) I did so because they showed a gold 
disk on the box, and they indicated a "Lifetime Warranty" on outer 
packaging as well.  It was only recently that I broke open one master 
pack and to my surprise, noticed the inner jewel case paperwork stated 
that the disk had a one year warranty from date of purchase (in other 
words, it had already passed).  However, the Jewel case image 

Re: filmscanners: Hazy bleed in hi contrast blacks on LS2000

2001-06-06 Thread Arthur Entlich

1st question:

How many people smoke near where the scanner is located?  Or cook fried 
foods?  Or was the unit moved that day from a cold to warm place?

The most common cause of halos in a scanner which seemed fine in the 
past, is an accumulation of residue on the lenses optics of ccd surface. 
Sometimes it could be water condensation from moving the scanner into a 
new environment or if you have a very steamy situation (hey, just what 
kind of images are these anyway ;-)) but if it is that, it will resolve 
in a few hours.

Of course, if you don't normally scan high contrast images with a lot of 
black, you might not have noticed that this problem was developing over 
time (residue on the optics).

Before panicking, however, it could be improper exposure.  All CCD 
scanners suffer from some blooming, and this can be made worse by 
incorrect setting causing overexposure, which can occur with a lot of 
black background and the scanner using autoexposure.  Assuming, however, 
that the part of the image that isn't black looks properly exposed, it 
likely isn't that.  If the non-black portion is overexposed, you need to 
reset the white and black points manually before scanning, and rescan.

Otherwise, it sounds like it may need a trip to your friendly Nikon 
service facility, which will likely charge you close to the resale value 
of the scanner to clean it. ;-)

Actually, I think they charge about $200 US.

Like any optical products, (and most electronic, as well) having them in 
smoky environments is asking for functional problems down the road.

I have not used either printer.  The 1280 is an upgrade(?) of the 1270, 
I believe.  Be aware that most of the high end Epson printers are now 
using the imbedded chip in the ink cartridge.  Unless you are going to 
use one of the techniques to defeat this (via software or hardware) you 
will be stuck with Epson's ink cartridges and their inks, meaning 
expense, narrow ink choices, and if Epson either goes bankrupt or 
decided to stop making your ink cart, you'd have an orphaned printer.

If any of these concern you, the newer Epson printers may not be a good 
idea.

The above situation is what I suspected might be the case, but, I'll 
give an example of the other side.  My UMAX scanner came with a DTC 
card, which Umax indicated would only work with their scanner.  UMAX 
North America's web site claimed the same thing.  However, on 
researching further the UMAX UK site was kind enough to mention that 
with a different driver, the card would work with most SCSI products and 
support up to 6 other devices, also.  It took some work to configure, 
since it required some jumpers be moved (I was luck that my card had the 
jumpers, apparently many versions didn't and one would have to cut or 
solder wires).  It does work, and I'm running my Zip drive on it, and my 
UMAX scanner.

You are confusing Acer with Microtek, who is the manufacturer of the

Not being a "Mac" person, I'm a bit out of my league, but Acer indicates 
the SCSI card they provide is "proprietary", and will not work with 
other devices.  I don't know if this is just a software driver matter, 
or if they really have some unique SCSI protocols.

Maybe Ed Hamrick can shed some light, since I think he's analyzed the

This is a good point, although the differences are getting "blurred" 
these days, as inkjets get faster, and the ink costs go up, and the dot 
size decreases.  Also the 6 color inkjets make the image so close to 
continuous tone, that again the lines are blurred.

With more archival inks for inkjets and better UV protective layers on 
Dyesub, the permanence is about the same.

Further still, there are a number of stand alone inkjet printers 
(Epson/Lexmark(under Kodak label)/HP (Photosmart series) now
on the market, that use an interface built in to them that you can slip 
the flash memory of a digital camera without a computer in between.

The main differences, practically speaking are:

Usually, cost of materials on Dye sub are higher, and they also are 
consistent.  Most use the same amount of materials if you are printing a 
dot in the center of a 8 x 10 sheet or a full image edge to edge. 
Inkjet printers use ink only where needed, not a dye sheet for each of 3 
or 4 colors (CMY or CMYK)

Usually, dye subs are limited to a maximum size in each dimension, which 
inkjets often allow for very long or unlimited length, but a limited width.

Dye sub require very specialized media, while inkjets can provide a 
great variety of papers.

Dye sub usually do a poor job with text, while inkjets provide very good 
text.  Most dye sub are 300-400 dpi, but provide true 24 bit (16 million 
color) per addressable dot, while inkjets are higher resolution, but 
require a number of dots to emulate full color.  That's why the text 
looks better on inkjet.

Speed is similar for similar sized images at this point.

Making test prints is very costly on a Dyesub, unless it uses special 
"ring around" software or some other type of test pattern (and usually 
still require a full page printout), because you can not make a "small" 
or partial print without using the full dye sheets.

Some dye sub printers have tried using ribbons of dye sheets rather than 
full continuous sheets, but they had problems with banding.

The benefit of inkjet (for me at least) is I can do tests using minimal 
consumables, over and over, if I need to in order to get very accurate 
color rendition.  I don't know if dye subs and ICC profiles have 
improved tremendously, but when Kodak was pushing them a few years box, 
they were having some problems with color management.  There is also 
less throw away waste with an inkjet, especially if you can recycle or 
refill your ink carts.

Re: filmscanners: RE: filmscanners: New Nikon performance

2001-06-08 Thread Arthur Entlich

I find it very interesting just how defensive most of the Nikon scanner 
owners are on this list.

The question below was a reasonable one.  Do the new Nikon scanners tend 
to amplify the dust and dirt when dICE is off, as they do on the older 
scanners?

All the sudden all these Nikon scanner owners are in love with dust, 
dirt, fingerprints and scratches, and want to see them as clearly as 
possible. ;-)

When the LS 2000 and LS 30 came out MANY of the owners mentioned that it 
was a good thing the Nikon's has dICE because the scans without them so 
amplified the dust, etc, that the scanner would be very difficult to use 
without the dICE feature, compared to other scanners they had used.

Somehow, dust and dirt and scratches have become some sort of virtue, or 
badge of courage that Nikon scanner owners proudly wear.

When lighting sources for photographic enlargers were introduced that 
reduced these bugaboos with minimal loss of resolution, everyone was 
happy to have them (well, except a few that preferred to spend half 
their lives doing retouching in color, and were using condenser lighting 
for color) but somehow its not the same with scanners.

The Nikons do slightly improve resolution (at least in the middle of the 
image) by using LED light sources and a unfiltered CCD, but, in so doing 
they make dust, et al, more obvious, unless you turn on the dICE, at 
which point you have a result that is likely softer than the equivalent 
scanner with a non-LED light source.

So, it appears there's no free lunch, but that doesn't mean my menu is 
better or worse than yours.  I do know that yours is more expensive.

I find this an interesting statement.  Maybe Nikon owners are more 
particulatetophobic?  I hardly ever hear from SS4000 owners complaining 
bitterly about spotting or wishing they had purchased a Nikon for dICE. 
  In fact, several have mused publicly about Nikon's owners comments 
about the absolute need for dICE on the Nikons.  To the point that 
resolution comparisons are made between the SS4000 scan (without dICE, 
since it isn't an option) and the Nikon scan WITH dICE as a fair base point.

I have no idea how much an IR channel and light source plus the ASF 
license add to the cost, but I would think Polaroid would have been 
browbeaten into providing dICE had it been such a problem without it.

I suppose its possible Polaroid owners are unwilling to admit they spend 
their nights at home doing dust spotting, since they laid out all that 
ca$h on the SS4000, but I'd expect someone would break ranks and blow 
the whistle.

Everything part of my intuition say the Nikon must have more surface 
defect emphasis without dICE than the others.  I don't have either 
scanner to work from, but I have read thousands of postings and this is 
certainly the impression I am left with even discounting company reps 
professional bias.

I'd love to hear from others who have experience with either or (even 
better) both scanners and who doesn't have an ongoing professional 
relationship with either or both manufacturers.

The 9000  ??" dye and 9500 ??" pigmented

But over time things have become completely ridiculous;

The 740, 750, 760 are 4 color (1440 dpi)

The 780, 880 and 980 which are 2880 dpi 4 color  (780 is new to me, so 
I'm jumping to conclusions here)

The 777 was a 4 color printer at 1440.

The 1280 (which I have yet to see) is probably an upgrade to the 1200.

(in which case, I made an error in an earlier posting as I indicated
the 1280 as an upgrade to the 1270.  I believe the 1290 is the upgrade 
to the 1270, and the 1280 is likely an upgrade to the 1200 at 2880 dpi)

I think I also saw a 1180, which would be a 2880 dpi upgrade to the 1160 
(4 color 11+ inch carriage).

The 870 and 1270 are 6 color "fade resistant" chipped cart, and I think 
the 890 and 1290 are the upgrades to them.  I don't know what they did 
to upgrade them.

The numbering system was further messed up by some method of 
distinguishing between the chipped and unchipped carts.

Even Epson customer service has a hard time keeping up these days.

I suggest you try Epson's website at www.epson.com

At one point the odd tens place meant a 6 color printer (750, 870, 1270, 
etc)  Then they came out with the 670 and 777, so that no longer 
complied.  Then the 70 and 80 and 90 was supposed to indicate the 
"chipped cart".  But the 900 and 980 use the same cart.

I don't know exactly what you mean by "do mini-labs "read" emulsion 
types before printing negs"

If you mean do they read for each subtle change of emulsion a 
manufacturer makes, then your answer is correct.

If you mean do they have a starting point that is based upon the 
emulsion dye base, the answer USED TO BE absolutely.  Our Noritsu unit 
had something like 32 "channels", each one was pre-programmed for a 
specific emulsion dye base.  As new emulsions became available, I 
programmed them myself, if they weren't provided by the manufacturer.

Today, I think newer machines just read the blank film area and make an 
automatic correction. With faster computers and more sophisticated 
software it is no longer really necessary to have a base filter pack 
programmed into the machine for each film type.  That means they do not 
correct for difference responses of the emulsion layers, or 
characteristics of the color balance of the film, but just attempt to 
come up with a "zero" point, so that if you were to make a print for a 
18% grey card, you'd get something approaching a print that looked like 
18% grey.

Unless one considers the sensitivity peculiarities of a specific film as 
a type of defect to be corrected for (all films suffer from their own 
versions of reciprocity errors, as well), then it would be best not to 
correct in complex profile of the film.  Kodak used to offer two 
versions of scans for PCD.  One was a base correction type that did not 
alter for film characteristics.  The other was an averaging type that 
attempted to make all films look the same regardless of the emulsion type.


The reason for this was simple.  For a pro photog who wanted to maintain 
the integrity of the film's characteristics, the base type was good, but 
for a person creating a PCD presentation where they had multiple sources 
(different age, emulsions and film types -including maybe both slides 
and negs) and they wanted some consistency of color throughout the 
presentation, then the second type of scan made more sense.

This is a philosophical issue.  Some photogs simply are after repeatable 
results, and do not want to either play with or emphasize the film 
characteristics, while others want the scan to represent the film image, 
and have chosen (or accidentally) gotten a result that works with the 
specific emulsion characteristics.  I know that sometimes an image has 
been pushed beyond my expectations due to the film doing something I 
wasn't anticipating, making it into a winner, while other times, upon 
reflection, I can look at an image and say "Gee, had I just used 
__ film instead, this would have been so much nicer."

More often than that, I say "Gee, had I just bracketed that a bit more, 
or had I just waited for the lighting to change a bit more, or had I 
just not used that lens, or that angle or that processor (who put a 
scratch in the middle of it!)..." you get the idea...

Although I haven't gotten to the point where I'm saying "Gee, if I had 
just remembered to recharge the batteries, put film in the camera, to 
remove the lens cap, or worse still, to bring my camera equipment!" I'm 
sure that will eventually happen.

I have had one "gee, if I had just remembered to rewind the film into 
the cassette BEFORE opening the back of the camera, that would have been 
a really good idea (or works "to that effect" ) ;-)

Actually, in case this happens to someone else (I'm SURE I'm the only 
photog who ever did it...) if you do happen to open the back of the 
camera before rewinding the film into the cassette (yes, I know, Canons 
work the other way around)  Quickly slam the camera back shut.  Believe 
it or not.  Film is relatively opaque before processing, and although 
you will lose your last frames and have some edge light fogging, most of 
the frames will likely survive... really!

Re: filmscanners: Ghosting on the Acer 2740S

2001-06-08 Thread Arthur Entlich

The fact that it occurs on multi-pass scans and not otherwise, seems to 
suggest an alignment problem.  The scanner might not be able to maintain 
perfect alignment with multiple passes.  Since I do not know if these 
scanners were designed for multi-pass I can't comment whether this is 
considered a defect or not.  However, the 2740S has to do at least two 
scans when it does dICE, because the IR scan is done separately from the 
visible light scan, so it should hold alignment at least for the two. 
I'm not sure the best way to determine if it is doing so, however, other 
than perhaps, placing both the IR and visible scan into photoshop and 
comparing channels.

To bring this into a slightly different realm...

Let's say you had a choice between a car which has a bit of vibration in 
the steering column, and tends to require just a bit of steering 
adjustment to keep it going perfectly straight, but handles over 
steering and other human aspects of imprecise driving without creating 
any real danger.

Then, on the other hand you had a choice of a car that had hardly any 
vibration in the steering and tended to handle somewhat better on the 
road as long as you used perfect driving habits, but if you over 
steered, for instance -(hey, your fault, right?) it skidded right off 
the road.

Which would you prefer to drive?

Being human, I'll take car number 1, thanks.

My approach to this is:

Scan in 36 bit, and capture as 48 bit scan.  Work in Photoshop in any 
aspect that works in 48 bit, and when all those aspects are adjusted, 
then convert to 24 bit.

Working in 48 bit provides extra "breathing space" in your ability to 
get good adjustments, but it is not without other problems.  Like, it 
requires a lot more memory, the processes are slowed down due to the 
extra number crunching necessary, and storage at that bit depth is 
painfully large.

The main things I have found that benefit from the full bit depth are 
levels and curves, contrast and brightness and hue/color balance adjustment.

For amateur use, all of this might be fairly moot, but you need to try 
both and see which you find acceptable.

I too noticed very minimal differences.  It probably allows for more 
forgiving prints if you have a slightly clogged nozzle, and helps to 
prevent banding more.  Overall it just seemed like me as a way to slow 
down the printers, with minimal return.

This is more specsmanship to be "bigger" than the competitors then about 
improved image. Since current stepper motors continue to get cheaper and 
finer, its a no cost option for Epson, IMHO.

I think Marvin makes an obvious but very significant point here.

A raw scan of a negative, should be negative, not positive.  Any manner 
of converting it into a positive means some type of profile has been 
actuated on it.

First off, please excuse the many typos and grammatical errors in posts 
of the other day.  I had no internet service for 3 days and then had to 
deal with a barrage of mail, and I was up until 4 AM answering them, as 
well, some personally quite stressful situations came up as well, just 
to keep the pot stirred.  I'm a bit more rested now, and might even be 
able to type a coherent posting or two...

I have a few ideas in regard to the issues of sharpness.  Has Nikon 
added "unsharp masking to their scan?  Before everyone jumps on me 
stating that the Nikon scan is pure and unadulterated and raw, let me 
qualify my statement.  If Nikon found a way to do unsharp masking that 
was not in "firmware" code or their software interface/driver could it 
still me called sharpening?

Isn't in fact true that the LED light source itself does a type of edge 
sharpening?  Could the use of certain cut off, trim, or bias filters in 
the electronics actually "sharpen" an image?

Is it possible the reason the Nikon can't be further sharpened without 
more artifacts be because it is being "optimized" in some other manner 
than through software?

David, would you be kind enough to post the same two images that you did 
previously, but this time using the unsharp masking you feel best 
"glorifies" the Agfa scan.

What I'm wanting to see, is how the dust and dirt responds to that 
processing in software.  Do we end up with very similar dust and dirt in 
both after sharpening?  Also, I want to see the overall tonal ranges you 
refer to.

The issue of Kodachrome and B&W with Nikon probably cannot be addressed 
easily.  Unless Nikon has developed a way to lessen the "native 
sharpening" that normally occurs, or ASF has developed a new way to deal 
with the IR scan (or the IR scan methods have been altered), I don't 
know of any way to make B&W or certain Kodachrome dye sets to become IR 
transparent.

Fuji is almost as bad as Minolta in naming their scanners, but not quite ;-)

I'm sure some of the product name confusion (in the film market) is no

Re: filmscanners: Hazy bleed in hi contrast blacks on LS2000

2001-06-14 Thread Arthur Entlich


I took a look at your scanned image (a nice image, BTW).  The fact that 
the flare only becomes visible on boosting levels, might mean you are 
experiencing blooming, which is why I asked in my earlier posting if the 
the exposure seemed correct.  However, there seems to be excessive 
blooming here, and I suspect this is due to contaminated surfaces on the 
optics (oil, smoke, etc.).  I guess the question is, is this s new 
problem or did it manifest this when it was first purchased?  Has it 
gotten worse over time?

On the off chance my post of about a week ago got lost in the gears, I
will repeat it here:

1st question:

How many people smoke near where the scanner is located?  Or cook fried
foods?  Or was the unit moved that day from a cold to warm place?

The most common cause of halos in a scanner which seemed fine in the
past, is an accumulation of residue on the lenses optics of ccd surface.
Sometimes it could be water condensation from moving the scanner into a
new environment or if you have a very steamy situation (hey, just what
kind of images are these anyway ;-)) but if it is that, it will resolve
in a few hours.

Of course, if you don't normally scan high contrast images with a lot of
black, you might not have noticed that this problem was developing over
time (residue on the optics).

Before panicking, however, it could be improper exposure.  All CCD
scanners suffer from some blooming, and this can be made worse by
incorrect setting causing overexposure, which can occur with a lot of
black background and the scanner using autoexposure.  Assuming, however,
that the part of the image that isn't black looks properly exposed, it
likely isn't that.  If the non-black portion is overexposed, you need to
reset the white and black points manually before scanning, and rescan.

Otherwise, it sounds like it may need a trip to your friendly Nikon
service facility, which will likely charge you close to the resale value
of the scanner to clean it. [;-)]

Actually, I think they charge about $200 US.

Like any optical products, (and most electronic, as well) having them in
smoky environments is asking for functional problems down the road.

Ebay is great.  I use it semi-regularly, but I have to say it can be a 
real PITA for people outside of the US.  Firstly, I'd guess at least 95% 
of the sellers will not sell to or ship out of the US.  The ones that 
do, charge huge fees to service clients out of the US.

Further, there appears to be an attitude that once they have your money, 
they can ship the item packaged in any manner they wish...

Of my last 3 purchases, (in the last month) two refused to ship to 
Canada, and I had to have them ship to my US drop off address.  Both 
shipments arrived damaged due to improper packaging (one went UPS one 
went USPS Priority Post).  One item was shipped direct here, and arrived 
intact, but only because I insisted on double boxing.

Customs problems and delays and duty costs abound.  Saying that ebay is 
a viable method of making purchases from outside the US is a bit like 
telling Timothy McViegh that Canada doesn't have the death penalty.

Re: filmscanners: BWP seeks scanner

2001-06-15 Thread Arthur Entlich

You don't directly mention the size of the prints you wish to produce,
although you allude with the 870 printer something like 8 x 12" or
smaller.  Unlike silver images, which simply have larger grain making up
the components of the image, without any true resolution loss, in the
digital realm, since even 4000 dpi scanners do not capture all that is
on a 35mm frame, you end up with softness and loss of detail if you go
too large.

If indeed you are going to keep to that 8" x 12" or smaller sizes, my
experience is that I get "grainy" B&W images with even a 2400 dpi
scanner when I enlarge to that size.  In fact, with unsharp masking,
which is necessary with any digital scan, you might find that with a
2700 dpi scanner, the grain of a 400 ISO film might even get exaggerated.

If you are mainly printing black and white, you might want to look at
Jon Cone's Piezography Inks, which allow for using four or six densities 
of black ink and special drivers to make very nice black and white prints.

Re: filmscanners: BWP seeks scanner

2001-06-17 Thread Arthur Entlich

I won't argue that CCD scanners do not typically capture the resolution
I am referring to.  In discussions with Phil Lippencott several years
ago, he indicated to me that a properly captured 35mm Kodachrome slide
(I'm not recalling if it was a 25 or 64 ISO film) could produce a
close to 150 meg file without adding noise to make the file that large.
I assume this was at 48 bit depth.  He was using a drum scanner, and
he told me that was about the number the thing plateaued out at.

I am relatively convinced good films with good lenses can record over
4000 dpi (as captured by a CCD scanner).  Part of this might well be
that a 4000 dpi CCD scanner doesn't come close to capturing 4000 dpi,
which I suspect is the case.  Since I know that the rated 2400 dpi HP
S-20 was "clocked in" at under 1000 dpi, I somehow doubt that the 4000
dpi models came close to that number either.

As I understand it, a CIS is a different sensor than a CCD.  It may well

Yes, Austin, that is how the Nikons work.  They have 4 sets of LEDs, R, 
G, B and IR.  It is, in part, why 1) Nikons tend to exaggerate the dust 
and dirt, and 2) why they have some problems with DOF on the edges due 
to the low LUX intensity of the LEDs, leading to the need for a very 
wide open lens not allowing for enough DOF for the curvature of much film.

As you probably know, the company Applied Science Fiction has at least 
three products for scanning use.  These are the components of dICE cube.

The one most people know, and the one which arrived on the scene first 
is dICE, which is a method of reducing the visible defects like dust, 
dirt, mold, scratches, fingerprints, etc.  This process requires that 
there be an infra-red scan channel as part of the hardware, plus some 
firmware and software to work.

GEM and ROC do not require hardware, but have to be "tuned" to the 
hardware they are used with.  So, in theory, any scanner could have GEM 
and ROC regardless of the hardware,  but it requires that Applied 
Science Fiction be hired to make the profiles, and that the scanner 
company pay a licensing fee to them.

Without getting into the acronyms, which I don't exactly recall, GEM is 
a software process which helps to eliminate the appearance of grain, 
without significantly softening the image, and ROC (return of color - 
that one I remember) is a method of analyzing the image color channels, 
recognizing the type of film emulsion, and then, again via software, 
adjusting the R, G and B levels to add back the expected fading or loss 
of color of some types of films to make it look more like the film prior 
to any fading.

In general, some of the older fixed focus lenses proved to have better 
glass, and if they are well multicoated they can be great.

One of my best lenses is a Nikkor 135 2.8 tele.  It is a Q series, which 
was a quality multicoated glass.

About 10-15 years ago, the SLR manufacturers recognized that the vast 
majority of images shot on 35mm film never made it beyond 4 x 6 or at 
most 5 x 7" prints.  As a result, they stopped trying to make lenses for 
the amateur market that resolved much more than what was necessary for 
those size prints.

Yes, the pro-level lenses at thousand$ each still maintain the qualities 
of those older lenses, but at mucho mas dinero.  But the general lenses 
available today with most 35mm cameras at several hundred of dollars 
each are slower lenses, compromise overall resolution when they are 
zooms, by keeping weight down and sometimes even using aspheric plastic 
molded lenses.  Also, some of the cams and mechanics in the lenses are 
sloppier or wear due to the materials used.

My best lenses, overall, are selected lenses I bought which were made in 
the 1960-70s.  Of course, they can't be made autofocus, so I compromise 
when I need that feature by using AF lenses.

Just hang around a while and you'll get plenty of this feedback.

However, happiness is a difficult emotion for film scanner users.

The desires and expectations, as the person becomes more educated, is 
difficult to maintain.

There are quite a few scanner owners on this list who have scanners 
between $600 and $1500, and in fact, I'd guess the vast majority fit 
there, because the vast majority of consumer CCD films scanners are in 
that price range now.

This forum is usually filled with people discussing the Acer 2710 and 
2740, the Minolta Dual Dimage and II Elite, Canon FS 2710 and the new 
4000 dpi model, the Nikon LS20, 2000, IV, the Polaroid SS4400... 
Everyone of these items costs less than $1500 US.

In regard to the complaints that get voiced, the software and hardware 
end of this biz are still maturing, and like most 35mm photogs, they 
wish they could afford a "blad".  But unlike "blads" the technology is 
getting better and cheaper all the time.

Oddly, Wilhem is considered the #1 authority on conventional film and
print permanence.  He has several books out of the subject.  He has
since been more interested in digital due to the huge demand for this
information.

As far as which will last longer, conventional versus inkjet output...
When using most OEM inks and papers, conventional photographic printing
is far more stable that inkjet.  However, if you use inks and paper
types specifically designed for longevity, the digital print *may* have
an advantage, which we will not truly know for hundreds of years.
Wilhem, for instance, identifies Cibachrome type two are having only a
17-19 year life before fading becomes most a potential issue.  He gives
higher points for inks, dyes or emulsion which fade evenly between their
colors to maintain neutral greys and blacks.  There are some ink and
paper types within the inkjet market which claim accelerated aging with
fading of over 200 years based upon the relative accuracy of any
accelerated testing processes.

Re: filmscanners: what defines this quality?

2001-06-20 Thread Arthur Entlich

I too was (and still am) fairly sure when I saw/see video versus film. 
I note even today that some TV shows use video while on the set, but 
will switch to film for outdoor shooting, and sometimes vice versa.

The way I'd define this difference is in a number of ways.  The obvious 
one is that film has a texture or grain, and the colors are usually less 
saturated, but more to the point film seems to have a wider range of 
color within any color breadth.  For instance, when I look as video shot 
of a face, I do not see nearly the numbers of "steps" of both shadow and 
color that make up the tones of "flesh" whatever that is.

With video, the pallet is much compressed.  I also find the contrast is 
higher with video, almost like it went through some "unsharp masking". 
Video also seems to be a cooler range of colors, leaning to the bluer 
spectrum.

Cibachrome prints of that era (especially the glossy ones), had a 
"liquid light" quality to them due to the thickness of the 'paper' 
emulsion and the polyester base which in the second generation used 
whipped air within the plastic base to create opacity to the paper, 
without using a dye in it.

Some years back I did a double blind test of some Leica and Nikkor 
lenses, looking at color rendition, sharpness, etc, shooting the exact 
same images on both at the same time on the same film.

I also invited several photographers and we looked at the slides 
projected with Navitar Gold lenses.  The conclusions were pretty much 
split 50-50% depending upon the lenses.  With the 28mm lenses the Leica 
shots looked great, the "normal lenses" had about 50-50% favor to each 
company, and the Nikon 135mm won hands down.

Well, I think this might just prove the opposite.  I think half of what 
made Ansel Adam's work so "agreeable" is that he was working with a 
large format neg.  Yes, his subject matter is "nice" and he certainly 
learned how to work with natural lighting to get the "most" out of the 
film, but the truth is his compositions are no better than hundreds of 
other photographers before, and since him.  I give him kudos for 
"schlepping" around a monster camera and tripod to those then out of 
reach locations, but that just made him a dedicated photographer and a 
pack mule (Oh-oh, I know I'm gonna pay for that one ;-))

What makes using an 8x10" neg gutsy is that it is equivalent to a 36 
exposure roll of 35mm film in cost and sq. inches, and again, when 
considering weight, each 8x10 film holder probably weights the 
equivalent of a good dozen or more 36 exposure 35mm rolls.  You have to 
feel pretty committed when you hit that shutter lever.  You also need a 
huge enlarger, to work from them, and also you probably do your own 
touch up since that size neg allows for it.

I'm not belittling the images of any large format photographer... I love 
the look, especially in B&W... and the dedication, but in part it is 
indeed the TOOL that makes the image, as much as, if not moreso than the 
technique.

Re: filmscanners: LED Illumination for Film Scanners

2001-06-20 Thread Arthur Entlich

Obviously, how evenly illuminated a field of light sources appears to be 
has to do with at what distance (or magnification) they are being viewed 
at, and through what media the light is being shown through.

There are all sorts of methods of mixing and baffling and diffusing that 
can blend illumination.  One could say a color CRT isn't evenly 
illuminated either, as it is bunch of lines or spots of varying 
phosphors and a shadow mask through which the electron guns activate the 
phosphors.  Yet, from a few feet away a good quality and properly 
aligned, converged and degaussed color CRT can look like a very pure 
field of white (or whatever other color) light.

So, without knowing how large the LEDs are, how bright they are, how 
close together they can be placed, how even their output, how closely 
they will be viewed and ultimately what their light is "processed 
through" I have no reason to believe they cannot produce even 
illumination for a specific application.

Has anyone actually seen the illumination system used in a Nikon 
scanner?  How large are the LED "elements"?  Are all four "colors" 
integrated into one LED element (R,G,B, IR), or are they individual? 
Are they diffused via some material or light chamber?

If I'm not mistaken, all A.C powered fluorescent bulbs "flicker" at 
60/50 cycle (in those places that use 60 or 50 cycle AC, that is).  In 
fact so do incandescent bulbs, for that matter, but in both cases, 
aspects of the design reduce the visibility of this.  I think television 
screens also do so at some frequency..., and we know that computer 
monitors do, and the higher the frequency the less obvious, at least on 
a conscious level.

In the case of fluorescents (and televisions and CRTs), the phosphors 
have a long enough lag activation period to "bridge" this rather short 
fraction of a second.  In the case of incandescents, the filament 
remains hot enough to bridge that difference in electrical flow.

I plead total ignorance in how DC powered bulbs fare, however.

Gee, 'big' minds seem to think alike.  I was actually looking into this 
myself.  I think the problem is that the TFT display doesn't provide the 
light source, just the color, so you are still having to provide a good 
constant color light source (cold cathode, I suppose).  Also, those LCD 
panels do have problems with color accuracy (which is why no one does 
color managed work with a LCD panel) and also there are still failed 
"pixels", something one would like to avoid in mission critical 
applications like scanning.

By the way, some of the index prints that are made by photo labs which 
come with APS rolls, for instance, use a negative digital mask made from 
a color LCD screen contact printed onto the photo paper.  Resolution is 
not great, but its an ingenious idea, IMHO.

OK, now I'm confused.  I thought taking ASA 200 film up three 'stops' 
meant 200 to 400 to 800 to 1600 ISO/ASA. As I understood "stops" it was 
an additional f-stop.  I thought each "full" f-stop more open increased 
the amount of light reaching the film by a factor of 2, which was also 
equivalent to one shutter speed position lower.  So, if I had a 200 ASA 
film without any pushing, and the perfect expose was 1/125th sec at 
f/5.6, that I could also take this same image at either 1/250th sec at 
f5.6 or at 1/125th sec at f4.0 if I had the film push processed for one 
additional stop, and so on.

Instead, it appears, Kodak is claiming for some reason (reciprocity 
failure??) 3 processing pushes are not equivalent to full "stops" and 
therefore one push is at 340 ASA, two pushes are at 640 ASA and three 
pushes are 1000 ASA, for a maximum of 2.5 stops for the three processing 
pushes.  Can someone enlighten me on this?

Since you use a lot of the pro version of this film, I have another 
question.  My wife has tried the Elite Chrome 200 on several occasions. 
  Each time she had it pushed (one push, shooting at 400 ASA) the 
results were variations of red shadows ranging from mildly pink, to 
downright ridiculous red Dmax.  Have you ever experienced this?  Could 
it be the film was damaged by heat or just a bad emulsion batch?

And, BTW, it does seem that shooting this film at ASA400 with one push 
is not a good idea, as her images were all underexposed by close to one

Re: filmscanners: line on Polaroid SS4000

2001-06-21 Thread Arthur Entlich

Before you give up on your scanner, or have to to cut and paste on the 
bad line every time, you might want to try to place your scanner on a 
different plane (try New York to LA ;-))  NO, seriously, try placing the 
scanner on its side and give it some gentle taps on all sides to 
dislodge any dust that might have fallen on the CCD.  Then put it back 
upright and try again.  It might just be a speck of dirt that needs to 
be "vacated".  If that gets you nowhere, then likely it is a defective 
CCD element, or a problem with the calibration process.

While on the subject of the "other cause" (a bad CCD element), I have a 
bone to pick with manufacturers about this.

I can think of no reason (other than a manufacturing defect) that can 
cause a failure of a CCD element, at least none that can be the caused 
by a user, other than perhaps excessive use.

I understand that the CCD can't be warranted forever, but it should 
provide some reasonable use without failing.  It is a known 
manufacturing problem that CCDs can have one or more weak or defective 
elements which fail prematurely.  If the person uses the scanner 
regularly, they will likely be covered under warranty, as it will fail 
prior to the one year anniversary, but if, as in the case of John, the 
scanner gets intermittent usage, well, then they get saddled with a huge 
repair bill.

This seems completely unfair to me.  A CCD sensor unit should be able to 
be reliable for several years, or more to the point, a certain number of 
scans.  I'm gonna bet that most scanners have something in the firmware 
that keeps track of the number of scans run through the unit, so the 
manufacturer could tell (and so could the user), and since the CCD plus 
labor is a major expense for replacement, I think a special CCD sensor 
warranty of say 3 years or 5000 scans (or whatever) would not be 
unreasonable.  Auto manufacturers do the same thing.

So which is the first manufacturer to step up to the plate? (BTW: Nikon 
should offer the same deal on their LED array!)

My reason for asking this actually had a purpose, beyond the humorous. 
Getting quality color processing for certain type of images can prove

If these images will never require reproduction in another form, such as 
printed hard (now I'm speaking glamour!, not as above, so no snickering) 
copy, then the digital will do well.  However, if you might be 
eventually selling images in other formats, or have clients who require 
other formats, unless you are using fairly expensive 'state of the art' 
cameras/backs, you might find you cannot get the quality your clients

Austin, this is why it sometimes is helpful to engage your obviously 
very capable brain rather than relying totally on written "fact".  I'm 
sure given a little thought, you'd have recognized the silliness
  of the 1000 hr number, considering how often we replace incandescent 
household light bulbs.  (then again, lately companies like GE seem to be 
happy with 100 hr bulbs or ones that just fail on power up, by that's 
another matter).  Can you imagine what problems in equipment failures 
would exist if LEDs lasted on average 1000 hr only?  I think Rafe gave 
some good examples of the huge number of devices we use which rely upon 
LEDs to sense locations, positioning, actuation or switching (how about 
most computer mouses, for instance).

Tell you one thing, I'm not buying any Stanley LEDs! (they must have 
gotten a great buy on these!) ;-)

I also expect, like incandescents and other illumination sources, LEDs 
can be built to different specs and be run under different electronic 
designs.  For instance, I know that with the halogen bulbs used in 
projectors, a "25 hr" bulb will last only 5-11 hours run at 125-130 
volts, will last 11-19 hours run at 120-125 volts, they last upwards of 
19-31 hrs run at 115-120 and if you use a dimmer to bring them down to 
about 105-110, they will last well over 50 hours, or nearly one order of 
magnitude from running at 125-130 volts.

> Your scanner should have a cited MTBF and MTTR, what are they?

Yes, that would be interesting, if they consider the light source 
separately, and not the whole unit.

Re: filmscanners: Digital vs Conventional Chemical Darkroom

2001-06-25 Thread Arthur Entlich

Since I was quoted on the bottom of this (I've edited it out), I want
to make it quite clear that on many occasions I have stated that I find
the number one problem with digital is the poor archival nature of
storage, so I am in total agreement with Karl.

The problem of change of format, no easy way to identify what is on the
disk/tape without a specialized (and maybe unavailable) reader, loss of
magnetic or optical data reliability in minimal time often causing a few
bytes worth of loss to render the total file or disk unreadable, etc,
all lead to the same problem.  Film is much more reliable.  All you need
is light to see it, a scratch is repairable without the full loss of
data, etc.

As I've said many times: show me a medium 1.5" x 1" x nearly zero, that
stores a readily accessible, 200 megs of info, which is also almost
fully archival with minimal care, and costs under 25 cents, and I'll be
ready to go fully digital.

Further, tell me of a more upgradable machine than a silver film based
35mm camera, which only needs a new roll of film (under $10) to take
advantage of the latest in photographic image taking...

Sure, I love digital, but no one should be fooled into thinking that
right now it is a "better" media in the above mentioned areas of cost or
reliability of storage, archiving and expense in upgrading.

Every time the density of storage media increases, this issue is (and 
probably needs to be) revisited.  I figure, with each doubling of 
storage density, there should be a doubling of reliability and 
permanence, since we are at least doubling our confidence in the product 
with the amount of material going onto it.

I do believe optical is better than magnetic, and if kept relatively 
safe of optical damage (from UV, intense lighting, etc), if the media is 
quality, it might even last a few dozen years...  However, coming up 
with multiple formats for the same media almost always creates all sorts 
of confusion.

Sorry Lynn, you are several months (which in this biz is centuries) out 
of date.

Epson (the printer people) with Cambridge Institute (I believe this is 
in Boston) have developed a method for using inkjet technology to spray 
some type of transistors onto substrates, to make a color panel which 
uses room reflective light source to create bright colored images that 
can be changed at will electronically.  It only requires an edge 
connector to be activated.

This stuff will be so cheap to produce within a few years, and can be 
sprayed on so many different substrates, that you'll being seeing video 
"Weakies" commercials on the cereal box in the grocery store, very 
likely in YOUR lifetime (as long as you don't do anything too strenuous 
;-))

And, BTW, as mentionedm, the more expensive version of this, using LCD 
technology is already available, but is only for people like Bill Gates, 
who has just such a thing.  Smaller versions are available for the 
little people (;-0) in places like "Sharper Image" catalogues.

Re: filmscanners: LED Illumination for Film Scanners

2001-06-25 Thread Arthur Entlich

Just two days ago, I was at a local retailer who showed me the new HP 
scanner/copier (which is basically an inkjet printer and a scanner on 
top).  It was only $399 CAN, and they have reduced the footprint to that 
of a small inkjet printer.  Pretty amazing.

The part that relates to this discussion, is that they were just setting 
it up, and that included a calibration process for the color and black 
ink heads.  It is now an automatic function.  The printer printed a set 
of varying matrixes and lines in both black and yellow.  The print head 
also had a very bright blue LED which went on, and I expect some type of 
sensor, which read the resultant printout.  When the blue LED was on, 
the yellow printing probably became gray, and the system probably tried 
to find the placement of the yellow and black lines which made for the 
highest contrast (which would be when the yellow and black lines printed 
on top of each other exactly).  I assume the unit than used this 
information to either physically adjust the head positioning, or to 
change the printing pattern to use certain nozzles and delays between 
the black and color cart, so that the ink would be printed onto the 
paper in registration.

It was a pretty neat idea, all made affordable by a blue LED.

Silly me, I used almost exclusively Kodachrome back in the 60's 70's and 
80's.  I only really moved to E-6 films after they convinced me I could 
trust them (in the 1990's), (other than Afga slides which used some 
weird process (CF??) which has failed completely on me, and will need to 
be dealt with via digital repair (for what is left of the image).  Even 
the Agfa stuff made me nervous enough to go back and reshoot on 
Kodachrome before I left the area (good intuition that time...)

I do have some 40+ year old slides from childhood that are looking 
pretty ratty and some negs from the 70's and early 80's that need a bit 
of help, but these are in the minority.

I think today's slides and negs (properly processed!!! and stored) will 
remain very effective images for a long time to come.  If they last as 
well as my 1970's Kodachromes, I'll be overjoyed.

Re: filmscanners: ScanWit Yellow stain

2001-06-25 Thread Arthur Entlich


Dear Jerry,

I just took a look at your attachment in Photoshop.  Of course, it is
heavily artifacted due to the downsampling and Jpegging.

The first thing I always do when I look at defects is to go into
channels and look at each channel as a separate entity.  In this case,
all the problems I am seeing are in the blue channel, but of course,
since the "stain" is yellowish, that would be expected.  I can see
considerable streaking in that area, which might either be the jpegging
or it might indicate some dirt or dust or calibration problem (or
defects) with the blue CCD.  It could also, however, be a defective
light source emphasizing the yellow end of the spectrum, which, of
course, would be picked up by the blue channel.

The first thing to do is to try to rule out that this defect is
actually on the film itself.  I would try two things to try to isolate
this.  1) put the neg into the scanner the other direction, or flipped,
so the left and right are reversed.  Since the worst of the
yellowing/darkening is on the right side currently, see if it become the
left side of the scan when you reverse the image.  If so, the problem is
likely the film itself. 2) If you can sacrifice a frame of this film
that is very overexposed, try mounting it in a slide mount at 90 degrees
and see if the problem is still in the same place (in relation to the
scanner) or not.  It might be that the processing developed the streaks
on the edges of the film and they are amplified by the overexposure.
Yet another possibility is that the scanner is running into it's limits
in dealing with the Dmax at those edges.  Between a small amount of
light falloff and possibly slightly darker film at the edges (film tends
to get developed along the edges due to the sprockets carrying a bit of
extra chemistry with them between chemical vats)  If the film was drum
developed, with a film reel, that would even make it worse, as chemistry
gets trapped in the reel), anyway, you might be hitting a threshold of
the scanner CCD or electronics which is being amplified by these factors.

Lastly, typically, repairs made during a warranty period where the
repair period caused the warranty to run out, usually carry some type of
further warranty from 90 days to 1 year.  Further, if a repair is not
effective, the warranty is considered extended until the repair is
completed plus an additional time for that repair (like 90 days).  Of
course, every country has its own legislation, and every company has its
own policies concerning these matters, but most enlightened governments,
like Holland, should have laws protecting consumers in these matters.

That's what I suspect, or that it uses some type of averaging process of 
several rows overlapped in the single row mode.

Further, I suspect the middle CCD strip is the most insulated from 
anomalies (electronic, and spill over).

This is sounding a lot like Epson's micro printing mode to eliminate 
banding during printing.  It seems it might be using the middle CCD row, 
which is probably most stable of the three.  As you said, it would slow 
things down quick a bit.

The dense scan banding brings back memories of my HP PhotoSmart... Seems 
CCD scanners still are not quite "there"... maybe a few more generations?

I tend to agree, but one nice feature of my Mastercard is a free double 
warranty on anything I buy on the card, up to an extra one year.  I pay 
nothing for this feature on the card.  I've yet to have to use it, but 
it feels a bit more secure to have a 180 day warranty widened to a year,

Yes, it is CT18 and CT20?, and they have all but disappeared.

And, one would "suspect" the processing was done properly, because the 
rolls were sent to Agfa Germany.  However, the rolls were so severely 
scratched during processing, that I have a difficult time believing they 
actually were processed in Germany.  There were several batches sent 
too, so it wasn't just one bad day.

Regarding the cellulose based films, apparently the Bettman collection 
Bill Gates bought is completely disintegrating, so they have given up on 
trying to scan most of them, since they claim it would take 25 years or 
more to accomplish and by then they will all be dust, ao they have moved 
the whole collection out of New York City and into some limestone caves 
somewhere, where maybe they will just "rest in peace" ?  They also made 
mention i the article of a strong smell of acetic acid.  AT first I 
thought they moved them just to keep the disaster out of the public eye, 
but maybe the coolness and alkaline nature of the limestone will slow 
down the process.  Of course, they could have just invested in some more 
employees and equipment and scanned the work a little faster...

Most scratches I have on B&W negs are not through the silver image, but 
either on the non-emulsion surface, or on the emulsion side, but not 
through it, so that light shows through.

That's one nasty type of scratch that literally goes through the silver 
image.

Obviously one problem with using these "clear" areas as a mask is that 
all clear areas would become part of the mask, not only the scratches.

Well, two comments,

1) film on polyester base probably is the best archival storage

2) Even film on cellulose acetate will keep itself together if properly 
stored.  The biggest danger is caused by overheated conditions.  Film 
should never be stored in 90 plus degrees F, as often occurs in 
apartments in cities in temperate zones during the summer.  Keep it 
cool, keep the humidity below 50% and constant, and your film will think 
it was at the spa, in fact, it might come out looking and feeling 
younger than when it went in ;-)

Re: filmscanners: why not digital minilabs?

2001-06-28 Thread Arthur Entlich

I think there are several issues with your approach.

The most obvious is availability of the service.  After that, there is
expense, going into an open loop system requiring more careful color
management, loss of control over final print, time spent going between
provider and one's business or home.

Also, of all the initial outlay expenses, the cheapest is the printer
(which is a pretty amazing thing if you think about it).

I think silver based digital systems are great when they are required,
but they change the work flow considerably.  I like having my color
printer two feet from my slides, my computer and my scanner. ;-)

Anyone who has been near a TV in the last month or two, at least in 
North America, has seen the Kodak camera ads which incorporate a digital 
image recorder AND normal 35mm or APS film.  The system allows you to 
review the last image (at least) taken by the camera (on film), and if 
it didn't work, you can shoot again.  This, to me is very innovative and 
smart use of technology, and not too costly either.  You don't need a 
lot of memory, as it probably only records the last shot taken.  The 
idea is not to keep the digital image, so it probably is not in high res 
either.  It does require a color LCD panel, but those small ones much 
cost a few bucks these days.  I wish my SLR had a device like that I 
could add to it, and if it were set up to mimic the basic 
characteristics of neg and or slide film, it would even reduce some of 
the need for bracketing.

Re: filmscanners: Minolta DiMAGE Scan & Dimage 7 camera

2001-06-28 Thread Arthur Entlich

I note that Sony has a new Digital camera which uses a nice little 3" 
CD-RW disk capable of storing about 150 megs of info, and of course, it 
is re-writable. The disks are about $5 each here (worth about $1.50, but 
that's supply and demand, I guess) Still a LOT cheaper than flash 
memory.  The camera in Canada is about $1400 right now, that should be 
well under $1000 US street, and saves the need for the extra interface 
with the computer, and having to download to write to a CD-RW/R anyway.

Of course, since CD-RW is reusable many times, to save money you could 
write the stuff down to a standard CD-R/RW and reuse the disks.  Also, 
the cost of packing a dozen of these 3" babies is under $60 CAN, and 
takes up very little space and weight.

I used to wonder about Sony when they came out with the floppy disk 
version of this concept, but now they are getting somewhere.  Of course, 
I imagine that flash memory is a lot more reliable (having no moving 
parts) than a CD-RW drive in the camera, and also RAM is smaller and 
must weight a lot less.  But one big advantage is at $5 a pop (or less) 
you also don't really need to bring a laptop with you and can wait to 
download the images when you get home.

This might be less of a problem than it appears.  Imagine you had a film 
which either had extremely wide exposure latitude, or could change ISO 
at will.  In effect, that is what the MOS/CCD sensors in a digital 
camera do.  They can move sensitivity levels within a wide range (much 
more than a couple of f-stops film can handle, with current film 
technology... Agfa and Kodak are working on new chemical techniques that 
could change this drastically)).  Digital sensors could even be set to 
decrease the exposure range, so that they compressed anything outside of 
their range.  Film can't do this, if you get over it's exposure range it 
simple blows out to Dmin and vice versa.

Photographic papers are even worse for this exposure latitude, which is 
why modern labs use digital enhancement techniques to improve prints 
from film.

If the exposure itself is "bang on center" within the sensitivity range 
of the sensors, then 8 bit/channel is probably al that is needed, as it 
is 16 million colors and hues, making for pretty much all the human eye 
can see.  The problem occurs when we squeeze this stuff up against one 
side or the other of the sensitivity range and then need to stretch it 
back out to fill that histogram space.  The we want all those extra 
levels to make smoother transitions to fix the loss of the color 
"resolution".

I'm not sure this is a problem.  Nikon and others have camera bodies

Any filtering of this nature would not be done at the lens level.  A 
lens is an optical device, and the best thing it can do is accurately 
translate everything it sees to the sensitive/recording layer.  This is 
what all lenses strive toward.  If any type of resolution lowering were 
to be required it would be done via electronic means.  Keep in mind film 
also has a "sampling rate", although it is somewhat more randomized and 
right now, still finer than most electronic sensors made available for 
mere mortals.

Re: filmscanners: Can the HP 7400 series match any of the dedicated film scanners?

2001-06-28 Thread Arthur Entlich

Hi Anthony,

I am sure you will get a number of different angles on this issue, and
most will be as valid as any other.

As good as flatbed scanners have become, they still, overall, do not
meet the quality of dedicated film scanners.  The only area where their
is overlap is in medium and larger format images, where the dedicated
scanners are quite expensive, so some of the top of the line flatbed
scanners which offer dedicated transparency drawers are similar in
quality.  But those scanners are both large and expensive.

The problems with flatbeds are firstly they are not really designed for
film which has a wide dynamic range and deep Dmax.  Also, most require
you scan through the glass which adds extra reflective layers, dirt and
possibly newton rings with film.

If you are working with 35mm film, I strongly recommend using two
dedicated scanners.  If you feel your flatbed doesn't give you the
quality of reflected image (from printed sources) that you require, you
might wish to upgrade it AND get a dedicated film scanner.  You can buy
600-1200 dpi scanners for well under $100 US now that do fantastic jobs,
so the cost there is really minimal.

In the area of dedicated film scanners, I can not in good conscience,
recommend the HP S-20 any longer.  In very nearly the same price range
you can buy the Minolta Scan Dimage II (USB) or the Canon FS 2710 (SCSI
II) (which I expect will further drop in price now that the FS4000 is
out there).  Even less expensive is the Acer Scanwit 2710 or for a bit
more the Scanwit 2740 which has digital ICE dust removal and IR scan
channel.  Some of the older Nikons (after the LS1000, which I would stay
away from) probably also would make you pleased.  The LS20 or LS30 are
examples, and they have IR channels and digital ICE dust removal, or
even the LS2000 used, although the owners of this scanner seem to still
be living in the pricing world of a year or more ago, and IMHO are
asking too much for them used, based upon new releases.  The older
Minolta Speedscan can be gotten used reasonably.

Ones I would stay away from at this point are are: HP Photosmart and HP
S-20, Minolta Dimage Scan (original SCSI model), Nikon LS 10, LS1000,
unless you get a very competitive price, and all the other 2400 dpi
scanners sold under several names (Jenotek, Tamarak, etc).  If you want
the best value in a really cheap film scanner, I suggest the 1800 dpi
Primescan, not because of the quality, which is marginal due to the 1800
dpi, but the price is right under $250 US).

To clarify, 'some' of the HP film scanners were good, but they had a
heck of a time with quality control, and I went through 3 of them before
giving up. HP was very nice about this, BTW, but who needs the grief.

The older Minoltas were not bad scanners, either, but if you are going
to buy into that class of scanner get at least one with 2700-2800 dpi.
The older Minoltas (I think other than the Speedscan) were all about
2400 dpi, which is just shy of making good 11 x 14 prints with inkjet
technology.

If you are considering the Acer scanners, look at ebay, since there is a
steady supply of new ones there at auction.

In fact, ebay is a good place to look overall, since there are pages of
film scanners for sale daily (used and new), and it will give you some
idea of pricing.

To look for film scanners, just type film scanners right into the main
search box on the opening home web page at www.ebay.com and they will
all show up.  Also, look at the completed auctions to get an idea where
the prices resolve.

Now is a good time to look as many people are upgrading to newer
scanners.  BUT, I will warn you that film scanners are not robust
devices, and they are expensive to repair.  It may well be worth your
while to buy new to get that 1 or more year warranty, dealer support and
manufacturer support.  There are very many things that can go wrong with
film scanners, and they even have a new out of box failure rate that is
higher than for many devices.  Buying used is relying a lot on trust and
the shipper not to mangle it.

I skimmed the article at the news stand, so didn't get the details.  I

Also, any magazine which does reviews and accepts advertising is suspect

Maybe the scanner is even worse than they claim, but with an average of,

Hi Norman,

I feel you pain ;-)

We may wish to carry on this discussion with me via private mail so we 
don't get too OT for the scanner list.

I'll do this part on the list simply in case some people want to chime 
in with further observations:

Here are my questions:

1) Which printer are you using, and what inks do you use?

2) Are you sending the images to the printer in CMYK or RGB format?

3) What printing settings are you using for the specific papers you use?

4) Have you attempted to adjust any of the printer driver settings or do 
you use them at default settings?

5) Under what lighting conditions do you view your monitor and your prints?

The blue purple spectrum with Epson printers is always tricky, and a 
custom profile might be the only answer (I have not done so myself, and 
the blues are never quite as I'd like them)

Don't assume the new printers are the answer, I get nice snappy prints 
using a 720 dpi Epson (Pro and Pro XL)

The image on the monitor is a "back-lighted" image.  You can never 
reproduce it on a piece of paper (until that light emitting polymer 
stuff comes out ;-))

The more I've worked with the name we pay extra to won, the more I

You might be onto something more significant than you give it credit for.

You should mention this to Nikon.  There are a number of possible 
problems here, from power supply issues (both regulation within the 
scanner as well as the quality of "juice" you are getting overall from 
your power company.  Also, there might be a synergistic effect here, as 
your computer and other peripherals that are involved in scanning 
(memory, CPU, hard drive, SCSI connection) may also be going into a 
semi-faint.

Also, keep in mind we are taking about very small increments of movement 
to create banding. Movement of the head in the scanner (due to viscosity 
changes of lubricants, dimensional changes of plastic and metal parts, 
the dimensionally of the lighting source LED network, the dimensionally 
of the film itself, etc, may all be changing more rapidly than normally 
or at least more extremely than under design and test conditions. 
Lastly, we know that CCDs work best under cool conditions.

So, power sources, power supplies, computer chips, peripherals, film 
stock and scanner components themselves could all enter into this.  If 
you have some air conditioning, why not try putting it on and see if 
lowering the room temperature helps to resolve the problems?

That better be polonium-210 not plutonium!  Plutonium is so dangerous 
one atom is enough to cause cancer.  It is used in nuclear power plants. 
  Polonium-210 (probably isn't pure, anyway) still isn't "safe" (no 
ionizing radiation is) it is probably similar in danger to Americium 
which is used in smoke detectors, but you don't keep a smoke detector 
next to your hand hold it regularly... and the problem of discarding it 
after you are done with it is a consideration as well...

Clean compressed air is probably a good method of dust removal.  You are 
right to be concerned about moisture and oil residue, but this can be 
controlled for.
