RE: filmscanners: File output format
Thanks Teemu. I will check your link, however I did search via Google and those I figured out mentioned that the TIFF internal data arrangement can be customized and depends on the source producer. This is the reason I asked about particular scanner.

Alex, have you tried searching the net for the TIFF file specification ? That might be more fruitful than asking here.

Alex writes ... ... what I'm missing is the information what is the unprocessed raw format straight from the scanner. 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)
