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.

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.
