Special Effects - shrinking a person
I watched this video to learn how to shrink a person as a special effect so I could make my own. In order to do this, I filmed the actor inside a rectangular cardboard box. I then filmed some footage of another cardboard box, wince was much smaller. In order to make this work, I the box had to also be rectangular so I could scale the size down. I then cropped the footage of the person in the larger box and layered it over the other footage of the smaller box.
