Is it possible somehow to get the color temperature information from RAW files with Exiv2 library? If not, it would be quite nice feature since some applications (eg digiKam) that uses Exiv2 could be much more useful.
ExifTool (by Phil Harvey) can do this, so maybe it would be possible to improve Exiv2 based on ExifTool.

thanks and regards,

I believe this is now supported. I pulled down a canon raw file from here: http://www.rawsamples.ch/index.php/en/canon

I have linked this to #992 which is a future project to throughly review and test our raw support.
