On my flatbed, yes. Usually at 150 dpi. But now with the FS2710 obviously I'm only doing slides and negs, which is what brought up all these questions. I guess I'm missing the point here. If I were to scan even a 4x6 print at 72 dpi, and then want to display it anything larger than 288x432 pixels, wouldn't interpolation be necessary? Even more with a slide or a negative? Ken
