A fundamental element of stereoscopic and/or autostereoscopic image production is the geometrical analysisof the shooting and viewing conditions in order to obtain a qualitative 3D perception experience. This paper firstlycompares the perceived depth with the shot scene depth from the viewing and shooting geometries for a coupleof shooting and rendering devices. This yields a depth distortion model whose parameters are expressed fromthe geometrical characteristics of shooting and rendering devices. Secondly, these expressions are inverted inorder to design convenient shooting layouts yielding chosen distortions on specific rendering devices. Thirdly,this design scheme provides three shooting technologies (3D computer graphics software, photo rail, and camerabox system) producing qualitative 3D content for various kinds of scenes (real or virtual, still or animated),complying with any prechosen distortion when rendered on any specific multiscopic technology or deviceformerly specified
