Hi Alfred. Thanks for your response.
It's a technique used by some landscape photographers, and is apparently a feature of Photoshop (which I don't have or use). It's used to create tinted lighting effects. I would like to replicate the process in AP, preferably in one step. Doing it in two steps (dodge, then add color) isn't quite the same thing, and is twice the work.
Carl123 - I have tried the color dodge blend mode in AP and couldn't figure out how to make it do what I wanted, which might be pilot error. I will watch the photoshop video you linked, and see if it leads me somewhere.
