You know, a picture of a room with one person sitting at a table, on a couch, and standing, or something like that, all the same person. Yes, it's played out, and not that tricky. But I've never done it. And I have no idea what to call it to look it up. Is there any trick to it other than making sure the lighting and speeds stay constant, taking multiple pictures, and layering in Photoshop then lassoing them in? I figure that's how I'd do it but I don't know if there's more to it. I know plenty of you have done it.
