RE: filmscanners: File output format

2001-12-18 Thread Alex Zabrovsky

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.

 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 ?)

Alex,

have you tried searching the net for the TIFF file specification ? That
might be more fruitful than asking here. The following came up pretty
easily with a google.com search:

Cheers,
Teemu.

  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)
