I want to be able to make fine tuning adjustments to a color checker either in the camera profiler package or in LR so that when an image in imported into LR it is accurate based on the bottom two rows of a Color Checker. Thus, once I have have a camera/lighting profile, if I shoot a color checker and import the raw file, the RGBYMC color wedges will be accurate to the Color Checker itself.
I found in CS3 that a curves layer and a selective color layer could be used for fine tuning.
Unfortunately, the RGB references in LF develop module are in % and there seems to be no way to control each channel individually. (If its in the LL Tutorial I missed it on the first viewing.)
The purpose for this effort is to be able to document works of art, works on paper as well as oil paintings and sculptures based on reference standard color "chips" based on the Macbeth Color Checker bottom two rows.
Naturally, doing this in LR has significant workflow benefits compared to going into CS3.
Hopefully this was a reasonable clear question: How can I fine tune the RGBYMC, and six gray scale wedges in LR develop module after making a camera profile using the Profile editor?
The objective is to get them to within .5% of the reference color checker that was photographed for the camera calibration.
Thanks for suggestions.
