This document contains summaries of three photography techniques: 3D photography can be created in Photoshop by removing the red channel, which gives photographs a 3D effect that looks better with 3D glasses. Multiple exposure involves overlaying two or more photos to create ghostly or mirrored images, such as a forest backdrop with a woman's face in front. High speed photography captures very fast movements, like cannonballs or strawberries being shot, that the human eye cannot see by taking many frames per second to reduce motion blur.
