Hi!
When I made a camera profile based on a mosaic DNG of the ColorChecker image ("Convert to linear" deselected in the Save dialog), it had a perfect visual match right out of the box. But then, PhotoAcute required linear DNGs. So I made a new profile based on a de-mosaiced DNG. The profile had not the same perfect match out of the box, but could easily be tweaked to have so. So I stored both profiles. Now, when I open a raw file in ACR, it makes no difference which camera profile I choose - neither visual nor in the histogram. It does make a difference if I choose eihter of these two versus ACR 4.4 versus 3.3. What is going on?

What version of Camera Raw are you using?

4.6.0.30. Sorry for not specifying this. As well as that I'm on a Mac 10.4.11.

Today I created a new profile based on a linear DNG of the CC image and did not tweak it. This profile makes a slight difference in the histogram, when I re-open the CC raw image in ACR.

-Good light!
