I'm working on a film in which several people are playing with a viewmaster (the orange toy that's used to view images). I want to be able to take some stills and make it look as though we are seeing inside the viewmaster and I want to do this within after effects. I have a viewmaster in front of me right now for reference and I can see how the images come in and out, and I know how to do the basics of animating things in after effects, but what I really want is some advice on how to make this look realistic. For example, when I look at the real viewmaster, it works by taking in light, so the images all look lit up from behind...how can I do that? What else should I know before I try doing this?
