The 126 cartridge was introduced by Kodak in 1963 along with a compatible range of cameras aimed at the lower end of the market.

The film is 35 mm wide but has only a single registration hole per frame, the image size is 28 x 28 mm. The film is contained in a sealed plastic cartridge, it is wound onto a take-up spool that is rotatable from outside the cartridge, the film in the feed part of the cartridge is not wound on a spool. The film has a continuous paper packing carrying the frame number which is visible through a window in the cartridge. A large, clear, window in the back of the camera shows the frame number and other information printed on the cartridge. The position of a small notch in the cartridge indicated the film speed which could be 'read' by the camera to set the metering system.

Disc Film was introduced by Kodak in 1982 along with a compatible range of cameras aimed at the lower end of the market.

Each exposure was 8 x 10 mm with 15 exposures on a disc. The film was held in a light-tight cassette which interfaced to the camera to operate the dark-slide and rotate the film in the cassette.

APS was introduced by Kodak in 1996.¹

The film is 24 mm wide with two irregularly spaced perforations per frame. The film also incorporates optical and magnetic recording areas that hold data on the exposure, described as the Information Exchange System, photo-finishers could add information. Each exposure had a size of 30.2 x 16.7 mm, one of three formats (aspect ratios) for the exposure could be chosen by the user:

• High Definition, 30.2 x 16.7 mm.
• Classic, 25.1 x 16.7.
• Panoramic, 30.2 x 9.5.

The film was contained within a cassette, placing the cassette in the camera moved the film into the exposure position by a 'Thrust mechanism' inside the cassette. It was automatically re-wound into the cassette on removal. The cassette could be removed before the film was completely exposed and later replaced without loss of a frame. On the end of the cassette were indicators showing the status of the film:

• O - unexposed.
• D - part exposed.
• X - fully exposed.
• a square symbol - processed.

Despite its very advanced specification APS did not prove very popular and was, in any case, overtaken by digital technology.
