Re: filmscanners: Emulsion flaws (was dust in SS4000)

2001-09-22 Thread RogerMillerPhoto
Roger, it would also be interesting if you exposed two identical rolls of film, sent one to a good lab for processing, and then processed the other yourself.  If the "bubbles" appear on both rolls, then they would be related to the film or the processing chemicals.  If they only appear on film that you process, then you would want to vary your processing technique until you found a way to make the bubbles go away.  I know that water, or a water based developing chemical, that is saturated with air and gases and has its temperature raised by even a few degrees will readily form small bubbles on anything submerged in it, including film, as the excess gas tries to escape the liquid.  That might account for the fact that you have an old roll of Kodachrome with "bubbles."  This is all speculation on my part.  The "dirt" that I once saw on several rolls of transparency film was to small to see with the na!
ked eye.  When scanned, it looked like small black spots.  I never looked at them with a microscope.  They were easy to remove with the clone tool without doing any damage to the image, but it was somewhat tedious.  I haven't had that problem since, but suspect contaminated processing chemicals.  I think that most of the problems people have with dust involve pieces large enough to see with the naked eye.  They can easily be removed with a brush.  But dirt and "bubbles" embedded in the film are not common and there's really no excuse for them.

For what it's worth, I sometimes go to the effort of boiling water for a few minutes if I want to use it to mix darkroom chemicals that I don't intend to use up right away. Boiling removes most of the air, oxygen, and gases from the water.  I let it cool in air tight bottles in the refrigerator before using it to mix chemicals.  You might try that if you think the bubbles on your film are due to gases precipitating onto the film during processing.  Like I said, I'm only speculating.  But if the bubbles are making it difficult to scan the film, I'd sure look for a solution to the problem rather than rely on something like ICE to fix a problem you shouldn't have in the first place.

What you have found offers a plausible explanation for the junk that has
been plaguing many of us although not seen or of concern to others.  I just
finished removing at least one thousand spots from a scan.  This was from a
pristine, perfect slide scanned on an SS 4000, blown up for a 13x19 print,
and rubber stamped in Photoshop.  Clearly, they were not the result of dust.
Nor was it from my brand new scanner.  The slide was processed by an
excellent lab.  The only explanation for this is that they are in the
emulsion.

Re: filmscanners: Emulsion flaws (was dust in SS4000)

2001-09-22 Thread Owen P. Evans

Hi Martin,
I can tell you that dust is everywhere! If you handle slides with cotton
gloves, the slides become filthy. If you place the slide into the slide
holder it will grab any dust that you let get on the holder while it sat on
the table. The minute the motors start whirring in the scanner, the
electrostatic charges pull dust in from all around the scanner. I scanned a
slide which I made a year ago and compared it to the scan of it I made 10
months ago. The slide sat in its Print File sleeve for 10 months. I cleaned
the slide with a sable artists brush, then compressed air ( Dust Off ) and
scanned it. The scan looked like I dumped an ashtray on the slide???
Compared to the first scan I made, it was worse.
My theory is that the slides themselves not only attract dust
electrostatically, but degrade and crack over time. These micro-cracks
aren't seen when we project the slides but under the microscopic scrutiny of
the scanner, become larger than life. Once the cracks open to the
atmosphere, all sorts of things can get into the emulsion layers of the
slide. Art & Roger are taking the manufacturers to task in their theories;
I'm just accepting the chemistry & physics.
Again, when we blow these slides up in Photoshop, they are magnified beyond
the 8 x 10" or 13 x 19" prints that we make so the spots become exaggerated
on the screen not in the prints. I've printed a lot of scans from the
SS-4000 to an Epson 2000P printer in the past 10 months and I don't see the
crud in the print; only on the CRT of the computer.
Just my two cents worth of opinion.

Owen

I just received my new SS 4000, and am wondering the same thing.
Silverfast seems to be pretty powerful, but cumbersome.  How does
it compare to Vuescan in quality (not just functionality)?  I'm looking
for the best quality scans, with minimal fuss.  The Polaroid software
is much easier to use than Silverfast, but doesn't offer nearly the 
amount of functions.  

The scanner is great so far - I just need to figure out how to use it

I have started to be pleased with the Sprintscan, especially considering the
$1,200 difference saved.  Unlike the Nikon, which has great software,
mastering PolaColor, Silverfast, and Vuescan, all having terrible
documentation, takes a good bit of time.  I am now getting very good scans
with better color than I got with the Nikon, albeit spending at least one
half an hour per scan to remove the spots.

I'm sure you're right about the fact that dust is everywhere and instantly
accumulates on any slide.  But I also agree with the view that a good deal
of the spots and crud are embedded in the emulsion, being either intrinsic
to the film or as a result of processing.  All these things together, of
course also including actual dust contribute to the problem.  So those of us
who don't want the spots will either have to go with ICE or spend a good
deal of time removing the spots.  At this point I can no longer say which
method is preferable.  If you have lots of free time, as I do, then it's
possible to work manually so long as you don't have lots of scans to work
on.  It seems to me that anyone who is doing quantity work would be foolish
not to go for ICE.

No doubt that the documentation is for hunger.  After recently returning a
Nikon Super coolscan 4000 and buying a SS 4000 with the goal of saving
$1200, I have a basis to compare the two and some advice on how to proceed.
The Nikon software is a pleasure to use, and the documentation, while
sparse, is clear and to the point.  As for the SS 4000, go with Vuescan.
Using both Polarscan and Silverfast, I got terrible results.  Using the
latest version of Vuescan with some help from those on the forum who are
proficient with it, I've gotten great scans with excellent color and detail.
I do wish that the documentation for it was clearer and gave more
information on how to set the various controls.

I can't really comment as I don't have and have never used Silverfast.  I

Martin,

I never got along with Insight software, and I bought mine way before Silverfast
was included ;-(
But, after initial confusion, I found Vuescan the best for Tmax 100. I find I like
to just pass the high bit image on through to Pshop. In fact, I wouldn't have
bought the SS 4000 if Vuescan didn't exist.

$$...Not only is the SS 4000 half price now, I had trouble with a previous
scanner...way back in 1995 a refurbed Nikon LS-3510AF went for $3800. I could
probably sell it for $300 now if I was lucky- but it's image quality is no where
near the SS 4000. And Nikon never fixed a serious bug in the (Win) software they
kept promising to do.
Grumble, grumble...

Hi Roger et al,
Interestingly enough, my best scans are from Provia 100F and 400F. I scanned
a few old Kodachrome 64 & 25's this afternoon and given their age (decades )
they weren't too bad. Compared to some recent Provia scans, they looked like
that ashtray's contents had fallen on them. Furthermore, when I spoke about
the micro-cracks I should have also included that I think airborne
particulate matter and fungal spores and any living organism can get into
the film layers. Perhaps pollution levels are the culprits here??
As a coincidence, Roger; I see your address at UNB and I know a Roger Smith
in the Chem. Dept. at Mt. Allison. Are you working at both campuses?

I'm wondering whether this phenomenon has any connection with something
mentioned to me by a lab when I complained about water marks on Kodak 100VS
slides.  The water marks were rings that had expanded from the sprocket
holes on the film before drying on the surface - and ruining some nice
sunset photos.  When I spoke to the lab, they said that Fuji and Kodak films
behaved quite differently in that chemistry tended to sit in the sprocket
holes on the kodak film - resulting in the rings - but didn't on Fuji film.
It sounds to me like the surface tensions of the films are very different.
If the bubbles are forming on the surface of the film (in the same plane as
the dust) then perhaps the higher surface tension of Kodak film "bonds" more
bubbles to the surface than on Fuji film.

Roger, I gather the bubbles are on the emulsion side of the film, not the
base side of the film?

I never used 100VS again - partly because of the rings, but also because of
the strange colour shifts in some of the photos.   Fuji films tend to
oversaturate, but at least the colours look more sensible!

filmscanners: SS4000 comments

2001-09-22 Thread Wire Moore

Just got a SS4000 to replace an LS-2000. After a day of use I find the
SS4000 is not as convenient as the LS-2000, but the scans are first rate! A
significant improvement over the LS-2000. Here are some observations:

- Got the unit from Micro Warehouse which charged US$100.00 more than eCost,
and took 10 days to deliver for $28.00. My cost will be US $581.00 after
rebate and including shipping. The LS-2000 was US $1700.00 when I bought it
in 1998. Micro Warehouse policy is there is a 15% restocking fee and no
return of open items. They refer open items directly to the manufacturer for
warrantee. At the point I decided to order, eCost had run out of stock. I
didn't grok Micro Warehouse's return policy until after I ordered. eCost has
since come back with a good price in stock. Drat. I haven't tried asking
Micro Warehouse to price match as their written policy shows total
disinterest in this sort of customer concern. I recommend you try elsewhere
first. (I'm done with my gripe session, now on to the scanner.)

- No edge focus issues like the LS0-2000 etc.; the SS4000 is sharp all
across the frame.

- SS4000 shows very much less grain than the LS-2000, allowing use of much
more unsharp mask. 

- SS4000 shadow performance exceeds the LS-2000 with 16x multi sampling.
Results are very good!

- SS4000 histograms are a tad compressed, unlike the LS-2000, but corrects
beautifully; superior exposure performance in spite of the Nikon's analogue
gain control (which was a very mixed bag). No problem with highlights
blowing out to get shadows.

- SS4000 color exceeds the LS-2000 in my opinion. SS4000 is a little
trickier to get good color saturation as compared to the LS-2000. But the
LS-2000 did very funky color for some reds, even when carefully color
managed. As I gain experience with the SS4000 software, I am finding minor
Photoshop levels and curves tweaks are all that's required for gorgeous
color. An Oversight when choosing this film type in Polacolor Insight had me
worried about the quality of the unit for a moment. I'm scanning Kodak Elite
Chrome (a variation of Ektacrhome 100). The Polacolor "Color Slide" film
setting is given good results.

- Dust is more of a problem for the SS4000 than the LS-2000 w/ICE, but the
LS-2000 wasn't perfect, even with ICE. Cleaning the film with a soft cloth
and canned air is effective for the SS4000.

- The SS4000 is physically faster than the Nikon, but SW processing takes
longer. Scans are quicker overall, even thought the SS4000 is 4000spi and
the LS-2000 is 2700. The SS4000 is much faster overall when compared to the
LS-2000 16x multisampling.

- The SS4000 SCSI connectors are two different types: one DB-25 and one
Centronics (and odd combination). The LS-2000 was a pair of SCSI-3 narrow
connectors, so I had to change cables. The SS4000 works fine in my long SCSI
chain (replacing the LS-2000). At first start after installation, the SS4000
logical device didn't appear on the chain, even after using SCSIProbe
utility to force a bus reset, but this problem went away after I
power-cycled the other devices on the chain.

- The SS4000 film holders are quirky, but usable. The Nikon HW is much
easier to use.

- 8 inches of clearance is required behind the SS4000 because the film
holder moves through the unit like a pipe, coming out the back.

- Polacolor Insight and Silerfast AI software are harder to use than Nikon
Scan and graceless in comparison. NikonScan V2.5.1 on Mac is the peak of
effective and attractive UI design IMHO. I miss it. A new user will find
Silverfast AI hopelessly daunting. Partly because the UI is designed for a
pre-press user and partly because pre-press users expect a bunch of stuff
that's irrelevant in a digital darkroom environment, such as support for
separations (CMYK). Both Polacolor Insight and Silverfast AI are giving nice
looking scans with a slight quality advantage to Polacolor Insight, but
likely only because I am still figuring out Silverfast. I haven't yet
profiled the scanner using Silverfast or Monaco EZ Color, so no comments on
this yet. Also haven't yet tried Vuescan yet. BTW--I'm not sure if the
following means anything, but I'll mention it anyway: The IT8 calibration
target that comes with Silverfast is different than the Kodak Q60E3. Whereas
the Kodak has a picture of a woman's face for visual skin tone assessment,
the Silverfast target has skin tone patches. I'm hoping this Silverfast IT8
is useful with Monaco EZ Color because the Q60E3 I've got is wilting.

- Multitasking the computer with the SS4000 is an issue as compared to the
LS-2000. Nikonscan 2.5.1 allowed normal response of the computer to other
programs while scanning, at the price of slower scanning in the background.
A nice trade-off. Polacolor Insight allows other work on the computer while
scanning, but foreground performance gets choppy. Silverfast AI takes over
the computer (Mac OS 9.2.1) so no other work can be done while scanning.
This is a drag.

Thanks for the info Wire.

I have a question about the different platforms for this scanner.  I ran
across a site with prices very close to the ecost price, but the description
read for MACs - no mention of PCs.  Are there two different versions of this
scanner or is the only difference in the installed software? (David??)  I
just unloaded my S20 and will be ordering the SS4000, I just want to be sure
I get the right package.  I am on  PC system.

Thanks in advance.

They are one in the same.  Both versions of the software
are included on the disk(s).  Just received mine yesterday,
and the bundle has it all (even includes three different
power cords - US, UK, and generic European plugs!).
Wire mentioned that the film/slide holders are flimsy -
the slide holder seems OK, but the film holder is 
awkward and flimsy enough that I ordered a spare.
