I am not sure what 8 samples per pixel would mean. 3 samples per pixel is reasonable for an RGB image, a fourth could indicate an alpha channel, but most people never see more than that unless they're into professional printing or even more specialized fields. > How is 1 SPP producing a grayscale image? Logical: there is 1 sample for every pixel. The sample represents the grey scale value (0..255) and is expressed in 8 bits (that is, 8 bits per sample). Gerben Vos.
