Try changing the focus option in Vuescan to Always instead of auto or

results in a different focus for each pass and fuzzes the result.  On the
LS2000 this may not happen as the multiscanning is single pass.

Eek!  I would *never* try scanning directly to a CDR.  That is bound to
result in buffer underruns and coasters.  A CDR is not a hard drive or a
floppy disk.  Packet software makes it *look* like one, but it isn't!

 It seems to me that the whole idea of CD burning is to avoid
 having to fill up the hard drive with images.

Yup, but it's not such a bad idea to check the image first before you burn
it to a write once medium.

Having said that, if you're using a TWAIN interface to scan into Photoshop
or some similar program, you've created a temp file on the hard drive. 
If you then save from Photoshop to the CDR it ought to work.  I don't have
packet writing software, so I can't try this.  On principle I would scan
a set of files until I had enough to put on a CDR (like 650MB) then burn
them all at once.  You won't get 650MB on a packet CDR because the formatting
takes up space.

 I realize that I could erase the image, but the procedure of
 copying to HD then to CD and then erasing the image on the
 HD seems very cumbersome.

Not really, especially if you're using drag and drop to do it.  If you highlight
a number of files, drag and drop them on the burner icon, you can then delete
them using the same selection once they've been written.  Personally I don't
use packet CDs anyway.

 The tech also suggested a ZIP drive.  I thought the purpose
 of the CD was to avoid having to get a ZIP drive.

A ZIP drive won't hold many scans, depending on what resolution
you're using.  The files also won't be readable on someone else's
computer unless they have the same model ZIP drive.  CDR is much
more universal.

That's normal.  You should see the options in the first tab, and it should
list the source device as your scanner.  If it says disk or something
other than your scanner, it's not seeing the device.Make sure you turn
on the scanner before you turn on the computer.

 None of the buttons (Preview, Scan, etc.) do anything.

 Should the VueScan software be loaded as a Photoshop plug-in?

No.  It doesn't work as a TWAIN application.  While on the subject, *never*
run the scanner's own software while Vuescan is running.  If you do, the
scanner will get confused and probably need to be switched off and on to
reset it.  Vuescan addresses the scanner directly via SCSI commands, so
any other program simultaneously trying to talk to the scanner will confuse
things.

 Is the trial version crippled in some way such that I

No.  The only thing which happens as a trial is that the
program puts lines across the scan.

I haven't used your particular scanner, so I can't comment specifically

Re: filmscanners: PS 6.0 v. PS 5.0 LE v. Jasc Paintshop Pro 7.02

 content here, that PS, and in particular PS 6.0, is the Rosetta stone,
 an essential professional tool for achieving image quality, and

It has a really good colour management system, and that is the best thing
going for it IMO.

 But what about lower-class people like me?  I'm an amateur, with very
 modest equipment (an Acer Scanwit 2740S and an Epson 900), very much
 in the learning mode.  Should I shell out the $500+ bucks, plus the
 learning time, to get a grip on 6.0?

IMO no.  It depends on how picky you are about getting a precise match
between the screen image and the page.  But you'll need more than just
Photoshop to do that...

 Will 5.0 LE serve me better, at
 least in the learning phase and possibly for all time?

Maybe, although AFAIK PS 5.0 LE has *no* colour management. It's also
missing quite a few other features.

 And what about the Jasc program?  It receives rave reviews in
 popular (i.e. non-professional) reviews, especially in computer
 publications, but I don't recall any reference to it in this list.
 Why not?

Most of the more vocal members of the list are professional photographers
who can justify the cost of Photoshop.  Like you, I find it hard to justify,
especially since I live in Australia where it costs over AUD$1300. I have
been using Paintshop Pro since version 4.x, and they're now up to 7.02.  PSP
7.02 does most things Photoshop can do, and some things PS *can't* do.  I
don't have PS 6.0 so I can't do a direct comparison, but one thing I prefer
in PSP is the page setup facility which allows you to visually place the
image on the page - the lack of a wiziwyg page setup facility in PS 5.5
stunned me considering the price of the program.

One *big* point in favour of JASC in my opinion - they have a newsgroup, and
employees of the company post there and read it.  They *do* take notice of
user suggestions.  The other people in the newsgroup can be very helpful if
you are trying to figure out how to do something with PSP.

 What capabilities is it missing, that I really ought to have in order
 to do quality work?

1) A high quality CMS.  PSP uses the Windows CMS which is ok but not
brilliant (others may feel otherwise :)
2) A soft proofing feature.  There *is* a soft proofing feature in PSP but
since it uses the Windows CMS, its accuracy is dubious.
3) The ability to uses colour spaces other than sRGB.  This may be important
with some colours, but I've never personally found it to be a serious
limitation.  PSP was mainly created with editing for the web in mind, hence
there was no need to support other colour spaces.  These days however, PSP
7.02 has some great tools for editing digital or scanned photos.
4) The ability to work in 16bit colour.  PSP can read a 16bit TIFF file, but
once the file is opened, all editing is in 8bits per channel.  I don't think
this is an issue with the Acer, but using Vuescan and my LS30 I can squeeze
10 bits per channel out of the scanner to tweak into a better 8 bit per
channel image.

Picture Window Pro is another cheap photo editing program which you might
consider in addition to PSP because it *does* support 16 bit editing.

http://www.dl-c.com/

 Put another way, how do I choose software that matches the
 capabilities of the rest of my system, and yet provides a reasonable
 path for future upgrade?

I'd say that the Acer scanner, Epson printer, Vuescan and PSP 7.02 will give
you great results.  Stick to sRGB for the colour space and let the printer
do automatic colour adjustment and you should get nice prints.  On the
other hand *don't* expect to get a precise match between the screen and the
page!  Doing real profiling and colour management is another whole kettle
of fish.

Rob

PS If you'd been able to take advantage of the upgrade prices when PS6 was

FWIW I use the crop tool in PSP to help with this.  Generally if I am rotating

outline using the crop tool with a side close to the line of the horizon,
and this gives me a reference to judge whether the rotation has worked.
 The PSP crop tool doesn't behave like the selection tool, so it's safe
to use in this way - otherwise you'd be rotating the selection.  You can
rotate by fractions of a degree - although I've never bothered with less

 1. With 200 film, is the grain large enough for the 2700 DPI to record

 If so could some one describe it (or email me a couple scan clips showing

Colour neg films have a random mixture of different sized dye clouds.  The
only C41 film I've scanned which showed no appreciable apparent grain in
mid-tones and highlights  was T400CN BW film exposed at EI250.
All other C41 films *seem* to show grain.  I don't think anyone one the
list has the exact figures to show the comparison between dye cloud size
and the area of a pixel at 2700dpi but from what I've read here, some are
approaching the same size.  Errors occur when the CCD elements see the
boundaries between different coloured dye clouds and these errors create
a random pattern resulting from the random pattern of dye clouds in the
film.  So what you see *isn't* actually the grain, but an interference
pattern based on the grain.

 2. Would you expect 1 stop down to be enough to see serious increase in
 grain in 200 film in these conditions?

Yes.  Referring back to the scans of T400 I see a serious increase in the
apparent grain in shadow areas of the same frame.  So I'd expect any
change in exposure with a C41 film to demonstrate a change in apparent
grain.  Define serious however. :)

 This weekend I am going to repeat the tests with a couple rolls of FUGI
 Provia 100F to see if the noise I am seeing FUGI 200 goes away.

With low contrast images in Provia 100F and a 2700 dpi scanner you
shouldn't see any significant artifacts caused by grain.  Higher contrast
images will probably start to generate problems with scanner noise in
the shadows but this is *not* anything to do with film grain aliasing.

For a more meaningful comparison of grain in C41 it probably makes
more sense to compare a 10x8 enlargement with a 2700dpi scan than
to look at a 6x4 print.

Not with a colour slide or negative film. Chromogenic films should be fine,
as should be slides but some of the more dense slide films may have problems
- eg. Kodachrome.  It depends on how much of the image is visible in Infra-red.
 Silver based BW film images are not transparent to IR so they don't work.

 Has anyone had observations or done any testing in this regard?
 Perhaps photographinq a high contrast texture or the white
 fluff from poplar trees floating in the air aqainst a dark

I haven't done a test like this but I have recently looked at the IR component
of scans from a number of different types of film.  The only respect in
which I've seen the real image being adversely affected by IR dust and scratch
removal is a softening of the image overall.

 I am currently stuck with an Artixscan 4000T which, of course,

No, the Artixscan 4000T and the Polaroid SS4000 don't have an IR channel.

filmscanners: Trying Nikonscan 3.1

2001-06-20 Thread Rob Geraghty

I've just tried Nikonscan 3.1 on my LS30 with a slide and a frame of Fuji
Superia 100.  Please bear in mind that's just two frames of film, so it's
hardly exhaustive.  I scanned the same frames using Vuescan 7.1 to produce
48bit colour and 16bit IR files of the same frames.  Here's what I found...

o Good news!  No jaggies so far.  But I have yet to try any of the frames
which were always a problem before.
o Nikonscan is way slower in the actual scanning process than Vuescan.
The only reason it was faster at getting an image from itself to Photoshop
is that it's TWAIN and dumped the image straight in.  Even so it's probably
slower overall.  I have no idea why focussing and exposure adjustment are so
much slower in Nikonscan than Vuescan.
o GEM and ROC are disabled.  Possibly they work better with 14 bits from the
newer scanners, but mostly I expect it's to encourage people to upgrade. :)
o Dust and scratch removal in Nikonscan and Vuescan was interesting to
compare.  Small scratches in some cases were minimised better by Nikonscan,
but generally the two programs were similar here.  Interestingly, Vuescan
was better at removing some large spots - they disappeared completely but
were still around in Nikonscan.  Both programs seemed equally effective at
dust removal.
o Colour - bizarre results!  The slide scan looked nice in Nikonscan but
closer investigation showed more colour and shadow detail in the Vuescan
output.  This isn't necessarily surprising since on the LS30 Vuescan
delivers 10bits per channel instead of only 8 from Nikonscan.  With the
slide, both programs produced nice results easily.  Nikonscan was a bit
quicker in terms of setting up the scan, but the end result from Vuescan was
better.  With Superia 100, the difference was staggering.  The output from
Nikonscan was oversaturated (and this coming from me - I like saturation
generally, but here the colours were really un-natural) and slightly
posterised due to the bit depth loss.  Tonal shading in the Vuescan image
was much smoother, and although the image looked flat initially, autolevels
and autocontrast in PS quickly fixed it.  So the Vuescan image required more
tweaking, but the end result was far better than the Nikonscan output.
o Interface - Nikonscan has changed quite a bit in the way it is laid out,
but the tools are actually quicker to get to.  I am still at a loss as to
why it defaults to 1350dpi instead of 2700dpi.

Fingers crossed that the jaggies have gone!  I'm impressed with the
improvements in Nikonscan 3.1.  However, for the LS30, Vuescan is still my
program of choice.  With other scanners that output more bits like the
LS2000 or more recent models, the differences may be more subtle.

 Ewa Marina make 'plastic bag' type housings which

I've looked at getting one of these to try with my Olympus compact camera,
but it's likely to work well at anything more than a metre or two because
of the water pressure.  If anything pushes on the Olympus' retractable flash,
the camera shuts down.  The problem with the Pentax would likely be focussing
accuracy through the bag and friction against the bag stopping the lens
motors from working correctly.  In any case I haven't succeeded in finding
anywhere that can get stock of the bag housings.

The bigger problem with taking photos underwater is light.  Red is lost
very rapidly, and the only way to get the proper colours back is to use
strobes.  At this point I just want a basic underwater camera so I'm looking
at the Sealife Reefmaster which is a compact camera in a housing and should
be about AUD$500 (US$250).  I will buy it initially without an external
strobe and add the strobe later.  The camera is pressure rated to about
50m I think.  I am also considering a trip to Japan, and if I went there
I may be able to get a Nikonos at a reasonable price.

What does this have to do with scanning?  The disposible underwater cameras
use 400ASA or 800ASA film and are pretty useless below 10 metres.  My experience
with the Fuji 800ASA camera is that even though it's only rated to 3 metres
it works down to almost 10 metres, but in average conditions the photos
end up very grainy when scanned.

Some digital cameras (eg. Sony) have underwater housings, but if you flood
it you're losing a $1500 digicam instead of a $200 compact camera.

Tony, I'll take your word for it that Fuji 800 is great when exposed at
EI650 but in the low light conditions where I've tried it, the results are
poor when scanned.  It's cool to be able to take photos at all with some
of the situations that Fuji 800 makes possible, but I generally find the
grain objectionable.

I just need to save up for that dedicated underwater camera. :)

I certainly have the impression that Ed's main use of the scanner is on

Ignorance is bliss? :)

 I would expect more input from people owning scanners
 in $600-$1500 price range. It is unfortunate.

I'm not exactly sure what you're referring to here, because there's no previous
text for reference.  Harking back to the post which started this thread,
I think there's been a lot of useful feedback.

As far as my LS30 is concerned, it's a great scanner with certain limitations.
 Unfortunately one of those limitations has been a bug in the Nikon software
which causes misalignment of scan lines.  Using Vuescan (which I only found
out about through this forum) the scans have no such problem.  The other
limiting factor of the LS30 is grain aliasing due to interference between
film grain and the CCD array sampling pattern.  This issue seems to be more
noticeable on the LS30 than other 2700dpi scanners purportedly due to the
collimated nature of the LED light source, but also I believe because the
Nikon scanner has much sharper focus than many other scanners.

Having an infrared channel is a godsend unless you have a LOT of time to
spend spotting scans.  While I'm sure everyone would like to think that
they look after their films, scanning has a tendency to show up the slightest
speck of dust.  The automated cleaning in Vuescan, or ICE in Nikonscan makes
scanning a LOT easier with a minor loss of sharpness.

I have made some excellent scans with the LS30.  LS30 scans of some of my
photos have been used in a commercial magazine.  If I am a vocal member
of the list, it's because to me US$800 (AUD$1600) is a significant investment
in hardware; my SLR with a 28-80 zoom only cost US$400.  I want to get the
most out of that investment, and I can't afford to simply sell it second
hand to run out and buy a newer one.

Most of the hassles I've had with film scanning have related to finding
out the limitations of the hard, software, colour management, and even more
importantly the limitations of 35mm films.  The simplest piece of advice
I think I could give anyone is to make sure your photos are as sharp as
you can make them, with the exposures as accurate as possible, on the finest
grain film you can afford.  At the end of the day, the quality of the source
material will determine a lot about the quality of the scanned result.

Choosing a scanner has a lot to do with what the buyer wants to do with
the results.  There's no single answer that is right for everyone.

the zoom function in Vuescan to adjust the edges to include the maximum
amount of the image without going over the edge of it.  For the first couple
of strips of film, this was fine, but the crop box now won't behave at all.
Here's a summary of what it's doing;

1) If I click in the middle of the crop box and try to drag the box, the top
edge of the crop box jumps down to where the cursor is and tries to drag the
top of the box.  Before clicking, the cursor looks like a hand.  After, it
looks like a corner drag arrow.

2) If I try to drag the left edge of the crop box, pointing at the edge
changes the cursor to a left-right arrow, but clicking and dragging makes
the top of the crop box jump down again as above.

3) If I try to drag the bottom edge up, the top jumps down again as above.

4) If I try to drag the right hand edge, same thing.

5) At one point I was able to drag the top edge up, but every time I went
back to the preview tab, the top edge bounced back down a couple of mm.
This lost me about the top 1/5 of the image.

As a result, I can't use the mouse to set the crop box at all.  Thinking
something may have gone screwy in the INI file, I deleted it, and
soft-rebooted the computer to ensure there was no previous remnant of the
program in memory.  The behaviour hasn't changed.  I've managed to get the
crop box maximised by manually adjusting the measurements in mm in the crop
tab, then looking back at the preview tab.  This was initially confusing
because with a normal landscape image, the x and y values are reversed -
ie. x is the vertical measurement on the screen and y is the horizontal.  To
Vuescan, a portrait layout is no rotation, so most photos require left or
right rotation, and afterward the relationship of x and y gets confusing.
Part of the problem seemed to be caused by large xy offsets.  I had to
experiment with reducing the offsets before I could get the crop box right.
I'm not sure how consistently the offset values behave - with the image
rotated to the right, the offsets seem to be from the top and right edges so
in portrait they would be from the left (x) and top (y)?

Zooming doesn't seem to help.  Also I've noticed that when zoomed it doesn't
seem to be possible to see the bottom edge of the crop area.  The bottom
edge of the crop box can't be seen with a full 35mm frame zoomed.

One small unrelated suggestion for vuescan; I would personally find it handy
if the final output display (the scan tab) was shown immediately *before*
writing the crop to disk.  As it is, I have to sit around for ages before I
get to see what the final crop actually looks like, instead I'm looking at
the previous scan.

Has anyone else experienced this strange behaviour of the crop box, or is it
only me?  Does anyone have any idea how to stop it?

Rob

PS Another misbehaviour of my PC *seems* to be related to Vuescan.  After
using Vuescan and closing it, an amount of about 20MB of RAM doesn't seem to
be freed.  More importantly, Win98SE won't shut down and switch the computer
off.  Instead it hangs at the Your computer is shutting down splash
screen.  On reboot (requiring power off or hard reset) the computer
bluescreens with a 0E error just at the point where the desktop comes up.
Hitting enter to close the program (god knows *which*), the dekstop comes up
OK.  If I restart (using shutdown/restart) at this point, the computer
restarts normally without the bluescreen.  If I shutdown instead, it shuts
down and switches off.  I was wondering what was triggering the bluescreen
as it seemed random, but I'm now convinced it's something about Vuescan's
use of memory.

Dan wrote:
 What are the best color and bw films in terms
 of scanning?

This is a question which I began attempting to quantify at least in the
sense of a guide if not actually a scientific way.  Unfortunately it's an
expensive and time consuming exercise to test every possible film in the
same conditions so a comparison can be made.

 From what I've read thus far, it sounds like
 Kodak Supra has a slight edge for color, and
 the C41 processed films (XP2 super and T400CN)
 for bw.  Are there others?

Using the LS30 I've tried Fuji Superia 100, Superia 400, Superia 800, Kodak
Gold 100 and Kodak Supra 100, as well as two varieties of Konica print 100ASA
film.  I'm told that Supra 100 is an older emulsion rebadged and not a new
formulation.  Supra 400 is apparently a new formulation which has been optimised
in some fashion for scanning, but I haven't had the opportunity to try it
as I can only buy it in packs of 5.

Fuji Superia 100, Superia 400 and Kodak Supra 100 all scan reasonably well.
 I prefer the colour response of Fuji films (OK so I actually like saturated
colour :).  However, particular areas of images seem to be problematic such
as bright skies which seem to show up grain (or apparent grain) more.

Kodak Gold 100 seems to have a ridiculous amount of grain.  The Konica films
didn't seem to scan as well as the Fuji films or Supra.

I have access to a SS4000 but haven't had the time to try selections of
the same films in the Polaroid to see if the aliasing behaviour is improved.

Apparent grain with Superia 800 is absolutely appalling, but it's still
possible to get useful low resolution images out of it.  Scanning some 800
last night I found it extremely difficult to use the curves tool in PS because
there's so much variation in the pixels due to grain aliasing.  Clicking
in an area that looks black (not zoomed 1:1) with the black eyedropper produces
enormous shifts in colour and brightness with fractional movement of the
mouse.

Essentially you should expect the maximum printable size of the image to
decrease with the increase in film speed.  This is just the same as using
an enlarger.  You want bigger prints, you use a slower film.

I have to scan some recent photos taken with T400CN to check out whether
the scanner sees more apparent grain than the enlarger.  I've done extreme
enlargements of T400 with the enlarger and the grain is amazingly fine.

All the slower slide films I've scanned produce far less aliasing or apparent
grain than print films of similar speeds.  The only slide film I've scanned
which had difficult grain was Kodak 320T, but the photos were not terribly
well exposed (existing light photos of a concert).

 Also, if one is planning ultimately to scan and maintain files
 in digital format (and print from there), are there any
 advantages left to shooting transparencies as opposed to
 negatives--given that the latter has so much more exposure
 latitude?  Or does the finer resolution of slide film still
 make this the preferred emulsion when scanning?

As Tony pointed out elsewhere, you have a fixed reference with slide film
but it's much more subjective with adjusting a neg scan.  The big thing
about slides for me is the vastly reduced apparent grain.  It's a personal
thing, but I'd prefer to lose a bit of shadow detail and maybe even highlight
detail to end up with an image that is much cleaner in the end.

I guess that's an important point; there's no one true answer to which
is better.  The answer will depend a lot on what your personal tastes are,
and what kind of photos you're taking.  If this wasn't true, there would
be a lot less types of film on the market.

I'd still like to post some more film comparisons on my web site, but I'd
probably need to figure out a more rigid and reproducible procedure for
taking the test images to avoid criticism of the methods.

filmscanners: Infrared scans on different films

2001-06-09 Thread Rob Geraghty

As a followup, here's a basic comparison between several kinds of films and
their behaviour with the infrared (IR) channel.  The thumbnails are tiny I
know, but they are big enough to show the important differences.  In IR, the
K64 slide shows quite a bit of image detail, especially on high contrast
edges.  Ilford FP4+ is very opaque to IR, with the result that it's hard to
see the dust and scratches for the image information.  Fujichrome 100 is
very transparent to IR, so that dust stands out in very high contrast, the
latter being opaque.  Scratches produce a much less distinct image in IR
(there is the beginning of a scratch 1/3 of the way up the right hand side
of the 1:1 sample).  This means that high contrast edges and scratches
look very similar in IR, and probably accounts for some softening of the
image when using IR cleaning algorithms.  Some grain still shows and this
also probably causes some softening.  I also scanned a frame of Fuji Superia
400 and the results were similar to Fujichrome 100, but Superia is probably
even more transparent to IR.  This explains why colour neg films or
chromogenic BW work well with ICE.

What the scan of FP4 makes me realise is that if you have a lot of BW
(non-chromogenic) film to scan, a Nikon scanner is probably a poor choice.
The Nikon will highlight every speck and scratch, and make for a lot of
spotting.  However, for C41 process films, the IR channel is a life-saver.

BTW in my minimal experience with Kodachrome, Vuescan cleans K64 scans quite
well, without the artifacts of ICE (I can't speak about ICE3).  In the above
tests, the clean filter in Vuescan had no noticeable effect on spots in
the Ilford FP4+, but then it also did *not* have any damaging effect.

From these results I'm guessing that it's quite easy to make a very
effective dust filter, but much harder to make a very effective scratch
filter which doesn't soften the image.

The tests were done with a Nikon LS30 and Vuescan 7.0.21.

That's an interesting way of looking at it.  I would have said the opposite;

 LZW is a near lossless compression. With the
 lower ISO film, you had less information. And, 
 not necessarily grain information in the 800
 film, you could well have greater gamut/saturation,
 greater light latitude in the 800 film. The Fuji
 800 films are now pretty darned good on grain size. 
 That's why you used the higher speed film, right?
 To get that information.

No, I used it because it's a fast film and I didn't have a choice when buying
a fuji disposible underwater camera. :)  Pretty darned good is a relative
thing.  The grain is OK when printed on photographic paper in a lab, but
it looks pretty darned awful when I scan it.

This is not a case of bad compression. Bad compression is where the 
algorithm assumes that - say - five pixels are the same, when they 
really aren't. Then, on expansion, these five pixels show up as the 
same. That is how you get smaller file sizes. You loose information.

As I mentioned in my original post I know about compression algorithms etc.
 Where I disagree with you is on the definition of information.  Yes,
the LZW TIFF of a Fuji 800 scan is bigger because there's more variation
between pixels and therefore little compression is possible without loss.
 However I disagree that grain (or grain aliasing) necessarily constitutes
useful information.

The print film is likely to have more data in terms of latitude, but a lot
less in other respects.  It's kind of like comparing a computer image of
320x200 pixels in 16 bit colour with another of 1024x768 in 8 bit colour.
 The first image can have a lot more tonal information, but the second has

filmscanners: OK, Vuescan is driving me nuts

2001-05-19 Thread Rob Geraghty

Am I the only one who has problems with the crop outline in Vuescan?  I have
been wondering why it is so incredibly difficult to position correctly.  I
*think* it's mostly due to one aspect of behaviour.  Let's say I'm cropping
an image in Paintshop Pro.  I click and drag to create a rough outline using
the crop tool.  Then I drag the edges (zoomed to 1:1 if necessary) to the
ideal position.  If I grab the side of the crop box, I can only adjust the
side.  If I grab the corner I can move two side at once.  If I click in the
middle I can move the box without resizing.

Vuescan appears to move the whole crop box sometimes when dragging one side.
This makes getting the outline right frustrating or impossible.  The
autocrop doesn't always eliminate strips of black at the edges of a frame,
and including them can greatly affect the exposure.

Has anyone else experienced this?  I'd have to say that the behaviour of the
crop box outline is the most frustrating feature of Vuescan.

I think this would have to be done by Tony Sleep, since it has been sent

Re: filmscanners: Stellar ghosts and Nikon Coolscan IVED (LS40)

 When I scan an image containing black sky and bright stellar images with a
 Nikon Coolscan IVED (=LS40) , then close to the edge of the field every
 bright (saturated) stellar image has a faint ghost image separated from
 the main image (by 20- 40 pixels).

Dumb question; I presume they aren't in the source image as reflections
in the telescope elements?  I get similar ghost images when I photograph
the moon.

Otherwise presumably they must be reflections in the lens elements of the
scanner. :-7

 I'm curious how you, or others, store their cds.

I have some folders with CD slip-sheets which I'm storing them in.
Keeps them in a much more compact state than normal jewel cases.

filmscanners: Paintshop Pro

2001-05-09 Thread Rob Geraghty

Someone recently gave PSP a plug on the list, and I was trying to remember
the neatest features which PSP 7 has over Photoshop.  Two which are
extremely useful are:

1) The ability to rotate an image a fraction of a degree

2) The redeye tool.  It allows you to replace the red eye reflection with a
fake coloured iris and pupil, complete with reflection spot.

There's lots of other great features - my favourite aspect of PSP is the
visual layout of printing.  I was astonished when I found out that Photoshop
5.5 didn't have an equivalent.

On the down side - everything is forced into sRGB, and PSP doesn't support
embedded profiles.  Windows CMS is supported however.

Rob

PS If you get PSP 7 make sure you download the appropriate 7.02 patch.

In which version?  Is it true for PS4, PS5, LE?  I don't
know.  I am assuming that you are using PS6.

Exactly what I suspect.  What is sad is that the sales and
support people in other countries and Nikon's own management
have insulated the engineers from being able to resolve the
issue.  Fixing it would result in a whole bunch of happier
users who would be more likely to buy future products.

As it is, I'll probably look to Polaroid next time.

 Please go away and leave us alone... we didn't create this
 problem and its Japan's fault. If they gave a rats ass,
 they would have fixed it long ago, since they've known
 about the problem for a long time.

I'm not convinced that the message has really got through to the programmers
who are actually writing the code.  I *am* convinced that people in Nikon
know about the problem *and* the solution, since they've loaned Ed Hamrick
Nikon scanners, and Ed has told them the solution.

I'd have thought that the programmers would have attempted to address the
problem in Nikonscan 3.0 if they'd actually been told about it.

 I know this is an accurate translation because it is exactly
 the line Epson and Honda and Roland gave me, and I've been
 waiting for a reply for over 20 years on a couple of them.

I'm disappointed you got a poor response from Roland.  I know
that the service department here in Australia was very
proactive in resolving issues.  They debugged a number of things
which Japan hadn't fixed.  But that was a long time ago when I
worked with them.

 If you really want some action on this, I suggest you
 contact a lawyer or at least your consumer affairs
 department.  Now that might get Nikon's attention...  in Japan!

In fairness to the local distributors I would need to raise
it with them before taking it to Consumer Affairs.  I also
seriously doubt that Consumer Affairs in Australia would want
to pursue something that affects so few people and would
require getting a response from Japan.

The response from Maxwell Optics would probably be to send
the unit back for repair, even though I know that there
is *nothing* they could do physically to fix the problem.
What is required is a software fix to a hardware design
fault.  Ed's done it, Nikon should be able to.

Supra 100 (!?)

It's been claimed here that only Supra 400 is a new formulaiton specifically
optimised for scanning.  Supra 100 is apparently a previous emulsion rebadged?
As far as apparent grain in sky is concerned, I haven't found Supra 100
to have any advantage over Fuji Superia 100 and the Fuji film is LOTS cheaper.
