I added a profile for the Canon EOS 5D Mark III to my collection of ICC profiles. The profile is still sub-optimal as the target was shot in non-ideal conditions. I will generate a better profile as soon as there is a day with clear sky and I am not in the office :-D
You can download the profile (along with the ones for 7D, 40D, 550D, and 350D) at the followin page:
Any feedback on the profiles will be appreciated.
I updated the 5D MkIII profile and I consider it as "stable" now. Please notice that, unlike the other profiles, I decided to make this profile linear: it seems to work slighlty better than non linear ones with the 5D.
