Levitation Photography

As we all should know, a levitation illusion is one in which a person appears to defy gravity by making an object or person float in the air. The subject may appear to levitate unassisted, or it may be performed with the aid of another object (such as a silver ball floating around a cloth)
Types includes :
1.)Acoustic levitation uses sound traveling through a fluid -- usually a gas -- to balance the force of gravity. On Earth, this can cause objects and materials to hover unsupported in the air. In space, it can hold objects steady so they don't move or drift.
2.) Magnetic levitation : this uses an aid of a magne or magnetic enabled device
3.)Levitation photography is a simple concept of layer masking in Photoshop. To break it down in simple terms, a picture of the scene is taken without any props and models. Later, several pictures are taken with the model and the props by suspending them in air
