[GRASSLIST:1478] GDAL with CIR-photos

[L. Junek]

Hi,
 I imported pseudocolor-Fotos with GDAL, they`re scanned as a *.jpg
 (o.k., this is maybe a challenge).
 As they always appear splittet into RGB-Channels, what about the
 Magenta, which is so important to handle the information in the
photos?
 I assume this color-information is splitted through additive
 colorcomposition into blue and red? So maybe the blue channel shows a
 part of the magenta color? 
Is there maybe a loss of information now using GDAL? 
Is there any experience on that, or does somebody know how the
 GDAL-library handles this?
