Are there cameras that allow channels to be checked seperately at the time of shooting?
1dsMKII and 1dMKII have color histograms. That would take care of normal blow outs in individual color channels. However nothing would ever show on a histogram for these color noise things I got a couple of times under very specific circumstances (shooting into the sun and very bright specular highlights on water and/or ice).
There just isn't any set of rules for shooting, composing, or processing that covers all possible scenarios. There's no substitute for experience, and lots of it. I won't get caught again by that situation that ruined a couple of sequences of shots, but who knows what further learning experiences are just around the corner?
