Re: [Digital BW] Understanding channel mixer

2005-02-18 by Clayton Jones

Hello Steve,

Dittos on what the others said.  I've found that if I stray very far
from a sum total of 100 that things begin to look "strange", but
there's no particular significance to + or - values.  I recently did a
formal portrait of a caucasian man and ended up with R=80, G=40,
B=-20.  

I also use a Hue/Sat layer for further adjustments after Ch-Mix.  It's
quick (if you can make up your mind <g>), easy, and allows a wide
variety of effects.

Also, in a recent landscape, before doing the BW conversion I first
intensified the Cyan just a tad.  It resulted in a darker sky right
out of the starting gate.  All that was required later was a modest
gradient.


Regards,
Clayton
