TTYL, DougF KG4LMZ< i don't understand either. the closest i can come to seeing what you showed was with my scans of Elite Chrome 400, but i also had Digital ICE enabled and that slightly softens the image and reduces chroma noise at the same time. i still think that i see less noise that you see, but i don't know why. one question that arose in my discussions with my Kodak contacts was whether the Canon scanner does one pass or three passes to get RGB values for a scan row. i presume one, but i can't tell from the Canon literature. another difference is that i always have multisampling 4X enabled and that reduces noise effects too. if it was aliasing effects because 4000dpi is reasonably close to clump size, you would see aliasing and moire effects on the scans. i didn't see any. try scanning an image that has a large even light tone and posting that. oh, and BTW, the contact asked me if the image was properly exposed according to ISO rating and i said i didn't know but assumed so.
