Levitation: action of rising or causing something to rise and hover in the air.Paranormal: Denoting events that are beyond the scope of normal scientific understanding.
A few important things you need to remember in order to create a successful levitation photograph is to make sure your background fits with the image of the person. You want to make sure the image looks natural and not just placed on a background. You also want to make sure you do a well enough job of cutting the person out so that it fits in with the background. In order to make the image look more natural, you might need to play around with things like lighting, shadows, and the actual placement of the image.
Some of my own ideas for making levitation photographs are to have someone sitting on water, have someone either falling off a bridge or a building, or having someone be jumping off of something.
