Hi Andy!
Digital ICE does not, I repeat, does not reduce the sharpness of an image.
What it can do is reduce the APPEARENT sharpness of an image. If you look at
two images side by side, with and without Digital ICE you will notice a
difference in sharpness. Many times the finest detail on an image will be
the surface defects; dust, scratches, etc. When these are removed the image
appears less sharp. Try it with a high resolution target, like progressively
closer lines. I doubt you will notice any difference in the resolution.

I ALWAYS use Digital ICE on my scans. If you think the image is a little
soft, you can always hit it with a little unsharp mask in Photoshop.

Since Vuescan doesn't use Digital ICE your results with that program may
vary.

If I have the time I usually use Digital ROC as well. It not only helps with
faded images but improves images with fluorescent and incandescent lighting
problems.

I usually scan at the native resolution (4000 dpi) and reduce the image size
in Photoshop if necessary.

Finally, again if I have time I use Digital GEM. It requires a lot of
processing time because it uses a very complex algorithm for removing noise.
It has the same reputation as Digital ICE because some people think it
removes detail. If you do a comparison you will find the same thing. Your
eye looks for the finest detail, which in this case is noise. With the noise
gone the image may appear less sharp but the fine detail is still present.
Again, hit it with some unsharp mask to make it appear sharper.

Good luck scanning.

Subject: [PRODIG] nikon 4000

Hi all,

Back on he list after a bit of a work binge. Need some tips on my nikon 4000
scanner..

Anyone using one regularly? Big step for me from a 25mb LS-1000...

I am scanning to full whack (4000dpi) via vuescan, with ICE off where
possible (as I understand this reduces sharpness significantly - true?).

Any top tips would be welcome with this machine.

Andy
