A camera comprises a camera body with a lens and shutter operating control and film cartridge removable from the camera body having an unexposed film spool region and an exposed film spool region and a bridging portion between those regions. An opening in the cartridge permits light from the lens to pass through the opening to the film at the bridging portion.

Cooperating elements on the camera body and the cartridge open the door or close the door with the door being openable when the cartridge is fully engaged with the camera body.
