Production Decisions

As illustrated in Fig.5, the cameras in the 3D rig may be configured to shoot (1) in parallel

mode (unconverged); (2) converged beyond the key object of interest in the scene; (3)

converged on the key object of interest in the scene; or (4) converged in front of the key

object of interest in the scene. The process of setting convergence involves toeing-in the

lenses of the cameras so that the right and left images of a particular target overlap. The

target for setting convergence may be an object in the scene or a slate held in front of, on

the plane of, or beyond the plane of a subject.

Fig.5 – Image Capture

The convergence point that is chosen by the filmmaker establishes the position of the zero

parallax plane in the image. This plane, as illustrated in the next sketch, will coincide in

position with the surface of the screen when the film is displayed (Fig.6).
