Hello Steve, Dittos on what the others said. I've found that if I stray very far from a sum total of 100 that things begin to look "strange", but there's no particular significance to + or - values. I recently did a formal portrait of a caucasian man and ended up with R=80, G=40, B=-20. I also use a Hue/Sat layer for further adjustments after Ch-Mix. It's quick (if you can make up your mind <g>), easy, and allows a wide variety of effects. Also, in a recent landscape, before doing the BW conversion I first intensified the Cyan just a tad. It resulted in a darker sky right out of the starting gate. All that was required later was a modest gradient.
