Abstract
A film holding cassette comprises a frame having film holding means for receiving and holding a photographic plate in a first position in the frame. The frame has track means for receiving a substantially light proof front cover plate for movement between a first position substantially overlying one side of the photographic plate, and a second position adjacent the first position wherein the cover plate does not overlie the photographic plate. The track means also receives a substantially light-proof back cover plate for movement between a first position substantially overlying the other side of the photographic plate to protect the photographic plate from exposure, and a second position adjacent the first position wherein the cover plate does not overlie the photographic plate to allow entry and removal of the photographic plate from the film holding means. The front cover plate includes means for detachably engaging its front edges to a light filter means associated with a camera, so that the light filter means occupies the first position substantially overlying one side of a photographic plate when the front cover plate is in its second position.
