Still trying to get to grips with CNX2 white balancing for skin tones. I understand that skin tones should result in R>G>B, with a ratio of [ 1 | 0.85 | 0.75 ] being 'reasonable'.
red top | blue bottom | neutral third left
However, most skin tone tutorials refer to corrections in CYMK but CNX2 gives us RAW development corrections with red-blue values only, although it does give us colour balance corrections with CYMK in the adjustment section.
What are the problems with performing development WB corrections with red and blue only?
