You probably ought to be addressing some scanner or software in particular (Vuescan?), but the data is almost always RGB (possibly IR) at a depth set by the scanner's firmware (8bit/channel, 10, 12, 14 ...). > Is the downloaded raw file TIFF only ? TIFF is the usual format. Regarding the other color space stuff, that would approach proprietary information, depending on who's software your speaking of. shAf :o)
