Abstract
A baffle apparatus for a large format camera to prevent non-imaging light coming from the object source and traversing the camera lens from reaching the image plane. A movable opaque baffle is disposed between the camera lens and the image plane. The object source location with respect to the lens and the required position of the opaque baffle are automatically controlled by means of cams driven by a common power source.
