Dieder-- Have you tried the same experiment with Digital ICE set in the "Normal" setting rather than "Fine"? I find virtually no image information when I do a difference between a "No Digital ICE" scan and a "Normal Digital ICE" scan.
I have been looking for some Nikon documentation on when to use "Normal" and when to use "Fine". So far I haven't found any. Do you have any information?

When those are removed >the image appears less sharp when actually the image detail remains. A simple test can provide the additional confirmation/refutation of this. Scan a negative with a film scanner that can do precise line repeat scanning, i.e. a film-scanner such as the LS-4000 etc. Do one scan with ICE on 'fine', another without 'ICE' pop both images into Photoshop. Superimpose one as a layer against the other and do a 'difference' mode for the layers. Images w/o ICE are noticeably sharper, though more dirty. For myself, it isn't that much of an issue except for a few scans so by default I use ICE, but for the most imp't scans, I don't use ICE and do scratch/detail repair by hand.
