Abstract
A digital cinematographic and projection process that provides a means of 3D stereoscopic imagery that is not adversely affected by the standard frame rate of 24 frames per second, as is the convention in the motion picture industry worldwide. A method for photographing and projecting moving images in three dimensions includes recording a moving image with a first and a second camera simultaneously and interleaving a plurality of frames recorded by the first camera with a plurality of frames recorded by the second camera. The step of interleaving includes retaining odd numbered frames recorded by the first camera and deleting the even numbered frames, retaining even numbered frames recorded by the second camera and deleting the odd numbered frames, and creating an image sequence by alternating the retained images from the first and second camera.
