Assuming I’m starting with a CMYK file, in the Channels window, I can select any one or a combination of the channels for an image. And if I do select more than one channel (say cyan and magenta), I’d be getting 100% of each.
I’m wondering how this relates to the Channel Mixer (CM). If I go into CM layer, select Monochrome, then if the source channels are at Cyan 100% and MYK are at 0%, would this be the same as viewing the Cyan channel in the Channels window?
And in CM layer with monochrome selected, if I had Cyan 66% and Black 37%, would this be like combining 66% of the Cyan channel with 37% of the Black channel?
And finally, in the Channel Mixer layer, the sliders go up to 200%, but I don’t understand how you get 200% of a grayscale tone when its already at or near black (100%) or white (0%). If I was viewing say 100% of the magenta source channel in CM, and some of the pixels were already showing 100% K, I don’t see how going up to 200% changes them, though it certainly would change some of the "lesser" pixels (for example at 55%, 67%, 12%, etc.)
Thanks, David
