Conceptually: it's 200% red minus 100% Cyan (B+G); therefore 100% R with 0G and 0B should look the same. Seth -----Original Message----- From: Steve Kale [mailto:stevekale@...] Wow sounds like a lot of work. I started playing with channel mixer as a result of some desaturated colour work - take a colour image and work it up to satisfaction, then apply a channel mixer layer with dramatic mix (eg Red 200%, Green -50%, Blue -50%) and then set the opacity of this layer at around 65% for a colour/B&W hybrid. I am still not conceptually getting what is happening when, with monochrome checked, a channel is set to greater than 100% or at a negative value.....but I like the results.
