RE: [Digital BW] Understanding channel mixer

I just want to add that "Desaturate" is still not the best way to convert to
B&W.  Learn to use Channel Mixer.

Also, most noise for low light or under exposed areas shows up in the blue
channel.  The less blue you use the better.
Just like film, the green is usually the best channel, so 40R60G or 35R65G
will usually be good.  EACH subject has its best setting.
