context_page_description: A camera magazine is a light-tight chamber or pair of chambers designed to hold film and move motion picture film stock before and after it has been exposed in the camera. In most movie cameras, the magazine is a removable piece of equipment.
  Many still photo cameras also have removable camera magazines. A film cartridge serves the same function, but is usually not reusable.
context_section_description: Another major categorization is the type of design: is the magazine one chamber or two chambers? If the latter, are the two horizontal or axial to each other? Most 35 mm camera magazines are one large chamber containing both spindles - usually the spindles are close enough together so that the feed and take-up rolls will just miss touching each other when the maximum length of film for that magazine is at its halfway point. Cameras with the single chamber magazine design include all Panavision and Moviecam cameras, most 35 mm Arri cameras, and all older 16 mm Arri cameras. Some old cameras, such as the Mitchell, have two separate chambers horizontal to each other, which looks very similar to a one chamber design. More popular today in two chamber design, however, are two chamber axial magazines, where the feed and take-up rolls (and thus chambers) are "stacked" one atop the other. Cameras with this magazine design in 16 mm include the Aaton and Arri SR models, and in 35 mm include the Arri BL and 535 models.
