I have some color photographs that I'd like to print using only two colors: black, and some shade of red. For example, here's a full-color image:
I've used Photoshop extensively, but only for certain tasks, and this is beyond what I've been able to figure out.
Is there a straightforward way to select a red color out of this image, and produce a new image that has only:
a black layer (or channel, or whatever, I'm out of my league) and
a red layer,
and see what the printed image would look like?
Thanks in advance for any suggestions.
