That value you quote (average 7 megs) for "your images" is quite high. I don't have PS7 (only PS5) : is the Quality factor 12 of PS7 less compressed that Quality factor 10 of PS5? (I've tried googling but not come up with anything authoratitive) I'm wondering also about differences in how well scanner images vs D10 images compress with TIFF and jpeg. To start with, the RAW output reflects the real information available. >From that, 3/4 of the information in the 8-bit per channel RGB files is fiction <grin> or at least interpolated. If you compress that intuitively it should compress better than real info because it is - indirectly - averaged. What are the pixel dimensions of the D10? 3088 * 2056 Effective 3152 * 2068 Total (never did find out what the extra pixels were doing) I'll try cropping some scanned images to those dimensions the saving them as TIFF / jpeg for a comparison. Let you know the results later Bob
