RE: [Digital BW] Understanding channel mixer

2005-02-17 by Seth

Conceptually: it's 200% red minus 100% Cyan (B+G); therefore 100% R with 0G
and 0B should look  the same.

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.
