ICC - Raw Info
« on: April 09, 2007, 09:32:45 AM »
Although using Adobe RGB Color Space in my camera settings, the Photo Mechanic's Info text dialog shows the ICC profile as sRGB for all my Raw pictures now.

I still have the PM's old version installed on another computer and, for the same pictures, the program shows Adobe RGB, which is the real information from my exif data.

Could you please fix this?

Regards,
Marta

Kirk,

This issue is preventing the extraction of Jpeg previews from Raw photos with the correct color space.

Will this bug be fixed?

Yes.  Likely in the first update.

Marta,

What changed in 4.5 is that we now pay attention to the Exif "interoperability" tags which specify sRGB or AdobeRGB (in addition to the Exif color space tag which comes earlier in the file).  Unfortunately, Canon marks the CR2 RAW file as R98 which is sRGB while the JPEG is marked as R03 which is AdobeRGB (these are the same photo shot in RAW + JPEG).

I've made a change to ignore the interoperability tags for RAW files when we know what the color space is already (i.e. Canon RAW files are marked as "uncalibrated" color space when they are shot in AdobeRGB).  This fixes the problem you are seeing.  It should also fix the color space of any extracted JPEG I think but I haven't tested this yet.

For now you can embed the AdobeRGB profile into the extracted JPEGs to set them straight (yes it is an extra step for now).
