Photographic film cartridge assemblies with removable filters

A film cartridge assembly adapted to be received for exposure in cameras of two types, one of said types having a predetermined exposure characteristic and the other of said types having an exposure characteristic other than the predetermined exposure characteristic, said cartridge assembly comprising:

• a cartridge body;
• photographic film in said cartridge body having a photographic characteristic matching the predetermined exposure characteristic of the one camera type;
• a filter removably carried by said cartridge body so as to be in the exposure light path to the film, said filter being adapted to compensate for the non-matching exposure characteristic of the other type of cameras;
• and
• means operable only in cameras of said one type for assuring removal of said filter from the cartridge body before the film in the assembly is exposed by the camera.

A film cartridge assembly adapted to be received for exposure in cameras of two types, one of said types having a predetermined exposure characteristic and the other of said types having an exposure characteristic other than the predetermined exposure characteristic, each of the camera types having means for removing a film cover from the cartridge assembly;

• said cartridge assembly comprising:
• a cartridge body;
• photographic film having a photographic characteristic matching the predetermined exposure characteristic of the one camera type;
• a film cover closing the exposure light path to the film for protecting the film from light;
• a filter carried by said cartridge body so as to be in the exposure light path to the film, said filter being adapted to compensate for the non-matching exposure characteristic of the other type of cameras;
• and
• means, so structured in relation to the film cover and the film cover removing means of only the one type camera, for assuring removal of said filter from the light path of such cameras before the film in the assembly is exposed by the camera.

A film cartridge assembly adapted to be received for exposure in cameras of two types, one of said types having exposure characteristics matching a predetermined film speed and the other of said types having exposure characteristics matched to a film speed slower than the predetermined film speed, said cartridge assembly comprising:

• a cartridge body;
• photographic film of the predetermined speed in said cartridge body;
• a neutral density filter carried by said cartridge body so as to be in the exposure light path to the film, said filter being adapted to compensate for the slower speed exposure characteristics of the other type of cameras;
• and
• means operable only with cameras of the one type of assuring removal of said filter from the light path of such cameras before film in the assembly is exposed by the camera.
