![]() The best results are obtained when you don't have to sharpen the image since sharpening by a function which is not ideally tailored to the imaging system distorts the final result. Contrast is lowered much earlier than at the resolution limit but it can be recovered by sharpening, though some problems do show up when you do this. Resolution is by definition the spatial frequency where signal equals noise. If someone is able to show me a 4800 ppi scan (unsharpened) where each pixel appears as random as on the Nikon, I'll send my Epson in for service the next day. That's when happens you have a good scanner able to recover some detail. Notice that on an LS-5000 with fine-grained film each pixel is sharply different from the neighbouring ones. Since so many people in this group claim that they don't see globs of pixels with similar values, I'd like to see some evidence. And a very, very large file with precious little information. ![]() ![]() If I scan at 4800 ppi on the Epson, all I get is large clusters of pixels with virtually identical values. It doesn't have to detail, grain in a 4800 ppi unsharpnened crop is good enough for me. I have the 4990 and Doug's holder, and also the associated glass. Ellis, please show me a crop of a 4990 scan which shows 4800 ppi resolution. ![]()
