I'm kind of new to polaroid cameras and haven't really had the chance to play around with them as only bought a Polaroid one Step P-Cam just recently. Also, the cost of the films are not exactly "fun" to play with.
I want to ask if there's any way to load a polaroid photo into a camera such that when I take a picture of my friend, the picture that comes out is a picture of Michael Jackson.
Err not sure if anyone get what I mean. Perhaps the videos below will explain better. Hope any polaroid camera pros can share any tips or tricks to modify a camera to create "magic" effects?
