[argyllcms] Profiling in-camera color transformation

Hi,

I'm trying to create an ICC profile which imitates to color
transformation done by my camera.

So I photographed an IT8 target, in RAW+JPG mode. Then I developed the
raw with UFRaw,
and converted to JPG to TIF with GIMP:

scanin -p -v -dipn -o IMG_4438_JPG.tif it8.cht
scanin -p -v -dipn IMG_4438.tif it8.cht IMG_4438_JPG.val

scanin: Error - Input file 'IMG_4438_JPG.val' doesn't contain field
XYZ_X or LAB_L

Is there a way to fix the above error? Can I have scanin produce XYZ_X
or LAB_L values?

Regards,
Pascal de Bruijn
