Does anyone know of freeware/cheapware green screen PHOTO software for the Mac? I have FCX for video, but I need something for photos. I'm sure I could just screen capture or export one frame from FCX, but I was hoping there was something like (but cheaper than) Aperture.
I'm doing a festival booth where I want to snap photos of people in front of green screens and superimpose their photos with worldly backgrounds and the print out photos to make it look like they traveled around the world.
