ABSTRACT:
Camera film has a pre-exposed image longitudinally thereon and is thereupon packaged into a canister for insertion into a camera. The canister carries a flexible masking strip. When the canister is inserted into the camera, the masking strip is spread across the camera film plane opening. As the film is advanced across the film plane opening for successive exposures, the masking strip prevents individual frame exposure of the previously exposed image. A masking insert can be alternatively inserted into the camera to mask the film edge.
