It doesn't need it. I don't use it. The ICE feature uses infrared light--in fact, you can scan film using red, green, blue, and infrared channels, if you wish (software such as VueScan gives you access to the infrared channel, although I haven't found a reason to use it). The Nikon uses LEDs as a light source for color consistency. They are passed through a diffuser, so the phenomenon you postulate does not occur. You can watch the scanner as it operates and see that the light source is diffused, not collimated. > At 3,5 or more, the Nikon is better than the 3.4 of > the Polaroid. The LS-2000 has a dynamic range of 3.6, the highest of any desktop scanner. It shows in the scans. It's very nice. As for this 4000-dpi scanner, is it possible that someone is confusing this with the LS-4500AF, Nikon's multiformat scanner that is available today? It scans up to 3000 dpi for 35mm, and it also scans up to 4x5-inch transparencies at up to 1000 dpi. -- Anthony
