Yes I have found the RT icc profile for the 5D, I can see only a subtle diference: the dark blues are less dark. I can see it in the nails, and (in other photographies) in the sky.
I also tried all the 37 DPP Profiles! I only can see two effects:
1- Some of them look very very dark
2- All the CNZ*.icc files look the same. The blues are more dark, and the red, and skin colors are only a little bit more yellow
Yes maybe you are right.
Some times I have some trouble for get the right colors in RT. But probably is my camera and the shooting conditions. I started as nature photographer using DPP because DPP got the best colors for my camera, Adobe Camera Raw and Lightroom are no the best for Nature photographie.
My question was my surprise about the diference 5000K-4650K
Now the question is clear, more o less…
I like RT and I use RT on PCLinuxOS almost exclusively in the last 3 years. Even for nature photographie
