Would you mind emailing me any pair of the profiles provided by Canon?
(Eg. fs.icc and fa.icc)

I wonder, how these are different. Generally, selecting the colour space
in the camera should not affect the RAW file (because it is raw data),
but it should affect the JPEG files only or be included in exif maker
notes to tell the vendor software to which colour space the raw should
be converted.

P.S. BTW, use of Canon's profiles may not be the best option since these
profiles were built for Canon's software, not for digiKam's raw
converter. However, if the output is satisfactory, it is better than
nothing.

Thanks,
