Rich, Thanks for explaining. That makes sense, and is a good idea to use the display for b/w preview. I must try this now. I was thinking that color blind people would prob. have an advantage in b/w composition. Yesterday I experimented w/this method of b/w conversion. I added a duplicate layer w/the blend mode set to color on top of the original converted to b/w channel mixed layer. I didn't notice any difference. I just now re-read what you said here and realized I didn't follow your instructions correctly. Typical of me...lol. Honest mistake though. You say do it all(channel mixer, set blend mode to color) in just one adjustment layer. I must try again... -Jeff :-)
