O.k., now this is not a 100% analog project I am being MADE to do here, but at least I am shooting on film... I need to print some images out on acetate. Ideally I would actually look at printing on glass and then hand-coloring, but time, money, and other things force me to go digital for output. Anywho, I got a "green screen" chroma-key backdrop and did some test shots. The problem is, with the one strobe I have, I get some obvious gradation and some light shadowing on the screen. Not TOO bad, but I would like to do better. Any hints on how to light such a beast? Ideally I want the image to "float" on a field of green.
