110 film

110 is a cartridge-based film format used in still photography. It was introduced by Kodak in 1972. 110 is essentially a miniaturised version of Kodak's earlier 126 film format. Each frame is 13 mm × 17 mm (0.51 in × 0.67 in), with one registration hole.

The film is fully housed in a plastic cartridge, which also registers the image when the film is advanced. There is a continuous backing paper, and the frame number and film type are visible through a window at the rear of the cartridge. The film does not need to be rewound and is very simple to load and unload. It is pre-exposed with frame lines and numbers, a feature intended to make it easier and more efficient for photofinishers to print.

Unlike later competing formats, such as disc and APS film, processed from 35 mm to 135mm negatives were returned in strips, without the original cartridge.

The 110 cartridge was introduced by Kodak in 1972 with Kodak Pocket Instamatic cameras. The new pocket-sized cameras became immediately popular, and soon displaced competing subminiature cameras, such as the Minolta 16 series, from the market. The 110 film width is 16 mm. A four frame strip measures 111 mm.

Fujifilm stopped manufacturing 110 in September 2009.Lomography re-commenced 110 film production in 2011. Lomography sell 110 Black and White, Colour negative, and Colour slide film.

Estes Industries has long marketed several model rockets, the most notable being the Astrocam, with a simple 110 camera in the nose; the shutter is triggered when the nose cone separates from the rocket body.

Although the format is most closely associated with cheaply produced, low-cost cameras, Canon, Minolta, Minox, Pentax, Rollei, Voigtländer, and others, as well as Kodak, offered sophisticated, expensive 110 cameras, with excellent multi-element focusing lenses and precise, electronically controlled exposure systems. Such cameras are capable of making high-quality images on 110 film. Some of these cameras are quite small and still hold appeal to subminiature-photography enthusiasts.
