A projector with two levels of illumination for projecting images from a film transparency is disclosed. Monitoring circuitry configures the level projector for the appropriate lead of illumination depending upon an operator request for preview illumination or a heightened level of illumination for exposure of a photograph of a composite optical image including the projected image. The monitoring circuitry also prevents excessive duration of illumination at the preview level.

An alignment mechanism for a detachably linked camera and projector for a front screen projection system is disclosed. The alignment mechanism, after initial adjustment, returns the camera and projector to the appropriate alignment for projecting optical images along the optical axis of the camera for recording composite optical images.
