RE: filmscanners: File output format

The friend of mine owns Minolta Scan Speed. Unfortunately, I didn't find
exact raw file format it downloads after the scan. It is referred as TIFF,
but what is exact data format inside in unclear.
I can only assume that this is RGB 24 or 36 bits/pixel, however I need to
know the exact color samples locations in related to each pixel location
(does the file looking like RGBRGBRGBRGB...
where each subsequent RGB samples express the pixel information ?)

  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 ...).

  TIFF is the usual format.  Regarding the other color space stuff, that
would approach proprietary information, depending on who's software your
speaking of.
