A camera comprising a chamber for receiving a film cartridge of the type having a snout portion provided with a film passage opening and an exterior information-bearing portion next to the snout portion, a door movable to close the chamber and having a window for viewing the information-bearing portion, and an elastic opaque gasket positioned around the window to be compressed against the film cartridge around the information-bearing portion to light-tightly confine ambient light entering the window when the door is closed, is characterized in that the gasket has a section positioned to be compressed against the snout portion of the film cartridge when the door is closed, and the door has at least one protuberance that projects into the section of the gasket to make compression of the gasket against the film cartridge greatest at the snout portion of the cartridge. By making the compression against the film cartridge greatest at the snout portion of the cartridge, rather than evenly applied against the cartridge, the orientation of the cartridge within the chamber can not be changed from the desired one.
