I used a Minolta FS2900 for a few years. It used the first version of Digital Ice. IMO, it was excellent. The only effect I saw on sharpness was in the areas where it interpolated to cover up dust or scratches. If you get a few scraches and dust specs together, it can have a pretty noticeable effect on sharpness.

When I tried Ice on silver B&W negs, the slide often came out blank or nearly blank (all white).

IMO, it is much better than the Canon FARE that came with the scanner I now use. FARE can't deal with hairs or scratches, and adds artifacts in the shadow areas of slides. Fare on "strong" is useless on slides.

Ed Hamrick has an IR based dust removal system in Vuescan that I think works quite well. Much better than FARE, and you can configure the promgram to show you what areas are detected as defects by the IR so you can see what will be "cleaned" off the slide.

The other day I saw how Digital Ice can remove imperfections
when scanning.  What wasn't clear to me is whether using DI
in any way "softens" the image.  As it was explained to me,
it shouldn't, but the fellow doing the explaining was new to
the technique himself, so I thought I'd ask here.

Also, I've heard the DI does not work well with conventional
B&W negatives.  Is that the case?  And, while on the subject
of B&W negatives, is it true that B&W does not scan well?
Last year I scanned quite a few B&W negatives and they
looked fine to my uneducated eye.

The scanner used in both situations was the Nikon Coolscan
IV ED super duper high end model, 4000dpi (sorry, I can't
keep track of all the model numbers).
