A 35-Mm Process Camera

This paper describes the unique features of the Acme Process Camera and their applications to special effects photography. Basic camera-design features include a color wheel for three-color successive-frame photography, interchangeable film movements with various locations of the register pins, a reflex viewer, embodying register pins in optical alignment with those of the film movement, projection facilities for “matte painting” which allow processed stock to be located on the register pins of the viewer and the image projected through the photographic objective. The electrical and mechanical operation of two new types of drive motors, the Acme stop-motion motor and the variable-speed synchronous motor, and their use in conjunction with the camera are also discussed.
