I'm trying to do something pretty simple, as usual I can't get it to work. While working on a picture
in LAB mode, I turned off the "A" channel, and it was a pretty nice effect. So I thought, I'd like to
save a version of this picture with those colours, unfortunately that doesn't seem to work.
You can switch them "A", "B" or "Luminance" off, make them invisible I guess, but they are always
So anyone any ideas how I can do this?
