I hope I describe this well to everyone's understanding. Lately I've seen some shots where you see multiple 'copies' of the same person in the same exposure. For example, you could consider a shot of a living room, with 3 or 4 different copies of yourself in the room doing different things. One copy of yourself could be sitting on the couch, #2 could be lying on the ground, #3 might be talking on the phone and #4 might be eating a pizza. Seems like a cool little gimmicky trick. I'd like to try it out!
My question is how do you pull this off?
This is what I suspect:
Say we want the above situation (living room). We tripod the camera and shoot 4 different exposures, with the subject engaging in those different activities for each shot. Then in PS, choose one particular exposure (any), and then simply cut and paste out the subject from the other exposures into the master exposure. The lighting should of course look natural since the subject in each different shot was shot with the same exposure settings and was in the exact same scene. It seems pretty easy, but I'm wondering if there was a better way.
Edit: So am I on the right track?
