Digital BW, The Print

And if you want the simpler and 16 bit savvy version just use the channel
mixer and enter the percent of blue, green and red channels you want with
the monochrome box checked...you can't split channels across the image this
way...but it works for most images that you don't need to do something
special to (e.g., fake a red filter on the sky and use a green for the
ground, etc.).
