Hi all. I'm looking for a color camera profile (Canon MKIII) for ACR 4.1. Mac.
Does anybody know if there are any around, or how to make one?
Thank you so much, Carlo

You can do it yourself, visit Tom Fors website and dowwnload his software ([a href=\"http://www.fors.net/chromoholics/]here[/url]).

Thanks Francois, it looks to me as a only Windows program!
No..., its a script. I'm going to try it in a second! Thanks again!

You cannot make a profile for use in CR or LR. You can tweak the existing two profiles using the fors script, on either Mac or Windows.

Cocasana,
It's a script and it runs in Photoshop. It works on both Macs and PCs.
Andrew is correct - of course -, it won't generate a real profile per se but tweaks to the two profiles used by Camera Raw.

OK - I'm lost... I thought the script was used to calibrate ACR after one had shot the Gretag colour checker.
What are these 2 profiles in ACR? I know LR has 2 presets - landscape and portrait. Am I confusing things?
I use ACR 4.1 and my Gretag arrived yesterday....was hoping for sun this weekend...after I locate an vacant grey parking lot at the top of a hill.

Essentially, ACR has 2 profiles built-in for each camera, one for illuminant D65 (a flavor of daylight) and illuminant A (similar to tungsten light bulb). ACR automatically interpolates between these based on your white balance.
When you fiddle with the calibration sliders in ACR, you are actually adjusting the RGB primaries of these profiles. In other words, you're not really creating a new profile from scratch; you are adjusting the existing ones. So there are limits to what can be achieved, but there is still some flexibility.
That is probably more low-level info than you really need. Essentially, photograph the target, and run the script ...

Yay, he finally updated it!
It's a good script, it really made a difference on my D200's.

Thank you Andrew, I got that! Thank you Francois, I did it.
I was eager to try the script, so I took a shot of the color checker and run the script and fiddled with ACR's setting to match everything. it was an overcast morning, then a wonderful sun came out and I repeated the operation. Now I have two presets. I will for sure use the second one, as recommended by Tom Fors, but I was thinking would it be wrong to have different profile for different light situations?
