My SS4000 is silky smooth with negatives. But the holder for the negatives

I understand your explanation perfectly, but it shows that in very contrasty
situations, you're better off chosing negatives than positives because the
positives will be more likely to saturate in both directions, the negative
capturing more of the total range. When I am shooting slides, there
Mike,
Back to your original problem... Why don't you at least try shooting it on Reala?
I had already written it down and plan to buy some on my next trip
to the "toy" store. I am always willing to try a different film and
see what I come up with. I have plenty of tungsten photo
Rob,
If the scratch is really sharp, it's the image
which is the problem.
Excellent. Scratching things is what I do best.

And with what I have I should be
able to get the LS-30 to produce a scan that is in focus.
A couple of points. First that scanning loses some sharpness due to aliasing, and you
should expect to apply a small amount of unsharp masking to retrieve crispness.
However
if you are doing this
Am I barking up the wrong tree here?
In theory, no. But in practice there's no apparent lack of tonal refinement when scans
from colour neg are printed (we are talking working with 16bit precision, I hope, not
8
bit). Though you can see a difference in tonality between fast and slow colour
I've got a problem with scanning at higher bits with Vuescan on my Canon
FS2710.
I am sure that in the past, when I have scanned slides, I have done so at 48
bit and then ended up with a Tiff file which is 36 bit in PS (maximum bit
depth on the scanner).
Now, when I scan, even set at 48bit in

Johnny, Tim,
The stated DMAX for the Perfection 1640 ($400) is 3.2. I don't have a lot
of data yet, but based on experience scanning very dark images on Kodachrome
120, it may be that good (for a cheapie) or close to it. As you indicate,
this is really a "dual 800" matrix CCD array, but the
Newton rings are circular contact marks that appear when using a glass
negative carrier to hold your negative under an enlarger. Does anyone
remember what an "enlarger" is.
what are Newton's rings?

sharp...!)

Hi Tim,
Maybe it is a bug in Ed's latest release. I suggest you send him an e-mail

Yes, probably a factor. Another possibility is the limited bit depth
of the LS30. This would be more of an issue on negs than slides due
to the compressed range of negatives.
Surely the bit range used by negs should be in the midrange of possible
values precisely because it is
