This is not true. All photographic file formats store R, G and B values for each pixel. Your display shows these at each pixel too (although some display types such as LCDs use subpixels that are next to each other that are R, G and B). You can sort of see those in this photograph: http://phred.org/~alex/pictures/scratch/reduced/IMGP1604.JPG That is a shot of text on a Dell 1702FP LCD monitor. It was shot with the *ist D and a reversed 50/1.4 lens. Remove "reduced" from the URL if you want to see the full resolution original. Most color scanners do capture R, G, and B for each pixel that they are scanning. alex
