Understood.Thanks Fotograz,
The solution you give me is good but not precise enough
With this one can only approach it visually but not with numbers to obtain exact values one want.
As seen in my attachment:
-First set measure points on white, second gray,4th gray, black patch and the first color to measure (I start always with yellow)
-second, in the Color Info-box you see the values you have at the moment (after neutralizing on second gray)
- In Color Correction-box:
I choose the channel to correct (this should have been Yellow, not Red, but it's just an example). With up/down arrows in the C,M,Y you can adjust until you get the 'right' values for that channel (until red is 230,green 195 and blue 62) in the ColorCorrection-box (see the 5th measure point)
- repeat this for the six basic colors of ColorChecker... becomes a very tydious work if you've several cards to profile.
As everiy one shoot paintings under diff lightings, every shoot starts with a new capture of the ColorChecker in front of the painting; once the card adjusted I copy the new settings on the next shot (painting without CCcard)...
Very tedious !!
But that kind of finesse I don't find in the color wheel of Phocus.
Maybe someone...
I never thought about it, but is the color checker the right tool for CMYK adjustments? Or is it universal?
Sounds like you need to start with a Multi-Shot file for better color separation and more faithful colors out of the starting gate?
If you find a precise solution that's easier, please post it.
