Here is a picture a friend of mine took during a music video shoot. If you look down below next to the BTS camera you will see a shoe and part of a leg that fades as it goes up. This is not a Photoshop trick or time exposure! If it were a time exposure, there would be another foot or portion of a body with shadows and this person would have to be moving pretty fast and still be able to keep his foot planted on the floor perfectly still. No one on the set had white shoes on! They didn't notice this until they downloaded the pictures to the computer. You can kind of see a little bit of a body behind the guy in shorts.
