ABSTRACT:
A sliding mirror mechanism is positionable in a first position to operatively engage a registration device to permit reticle masking for multi image photographs and in a second position to operatively cooperate with a rotary shutter to expose a strip of film to make the photograph. An interchangeable flip mirror shutter mechanism, operatively combinable with the registration device, can be substituted for the sliding mirror mechanism. In a first position, the mirror of the flip mirror shutter mechanism cooperates with the registration device to compose the image to be photographed and in a second position exposes the strip of film to make the photograph. Each of a pair of film boxes is keyed to the camera and removably retained by a pivoting lever. An independent pivotally mounted direct drive motor associated with each film box selectively urges rotation of a reel attached driven wheel with a drive wheel.
