126 is the number given to a cartridge-based film format used in still photography. It was introduced by Kodak in 1963, and is associated mainly with low-end point-and-shoot cameras, particularly Kodak's own Instamatic series of cameras.
Although 126 was once very popular, as of 2008[update] it is no longer manufactured, and few photofinishers will process it.

In 1963, Kodak introduced a new film, encased in a plastic cartridge, for which they re-introduced the "126" designation. (The number was originally used for the unrelated 126 roll film format from 1906 to 1949). The term "126" was intended to show that images were 26mm square, using Kodak's common 1xx film numbering system. However the image size is actually 28 × 28 mm, but usually reduced to approximately 26.5 × 26.5 mm by masking during printing or mounting.
The 126 film format was defined in ISO 3029, which has since been withdrawn.
Like the 120 format, there is a continuous backing paper, and the frame number is visible through a small window at the rear of the cartridge. Cameras for this type of film were equipped with a larger rectangular window in the back door, through which was visible not only the frame number, but also a portion of the label showing the film type and speed. The cartridge has a captive take-up spool, but no supply spool: the film and backing paper are simply coiled tightly and placed in the supply end of the cartridge. The positioning of the image is fixed by the cartridge. The film is 35mm wide, but unlike 135 film, it is unperforated, except for one registration hole per image, similar to the earlier 828 film. The camera is equipped with a sensing pin which falls into this hole when the film is fully advanced to the next frame, at which point the winding knob or lever is locked, so as to prevent winding past the pre-exposed frame lines.
The top edge of the cartridge above the film gate has a square notch in a specific position corresponding to the speed of the film in the cartridge. Some of the higher-end cameras used this notch to determine the correct exposure, or to set the light meter, if so equipped. Although only film with speeds between ISO 64/19° and ISO 400/27° were ever manufactured in this format, the standard defined 20 different speeds, from ISO 20/14° to ISO 1600/33°.[1]
The film was originally available in 12 and 20 image lengths; at the time regular production stopped it was only available in 24 exposure cartridges. The film does not need to be rewound, and is very simple to load and unload.
The format was introduced by Kodak under the brand name Kodapak, together with the Instamatic camera. Although the Instamatic name is sometimes treated as synonymous with the 126 format, Kodak also used it on its later 110-format cameras, which they called Pocket Instamatic and on its "M" series 8mm movie cameras.[2]
Around ten million cameras were made by Kodak and other companies. However, with a few exceptions, the format was mainly used for fairly simple amateur cameras. (Makers of the few high-end models included Kodak, Minolta, Rollei, Yashica and Zeiss Ikon.) Kodak officially discontinued the format on 31 December 1999.[3]
Ferrania[4]inItaly, was the last factory producing 126 film. Their product was an ISO 200 colour print film marketed under their Solaris brand. The last scheduled production run took place in April 2007, but an unscheduled production run in late 2007 surprised industry observers and raised hopes that it had not actually been discontinued.[5] As of March 2009, Ferrania customer service states that they are producing only 135 format color film in 200 and 400 ASA.
Adocolor 126, which was until recently available in Europe and was sometimes imported by North American resellers, was manufactured for the German Adox company by Ferrania. Ferrania and Adox are currently in negotiations to transfer the relevant production moulds, tooling, etcetera... to Adox so production can start again. Adox had been hoping to release it in January 2012; however, the latest information on their website as of May 2012 states that the film is still out of production, and that they do not know if or when that status will change.[6]
Because it is 35mm wide and is developed in industry-standard C-41 process chemistry, processing of currently available 126 films is readily available, as long as the photofinisher knows that it is standard, 35mm, C-41 film. Many photofinishers are not aware of this, so it may be important to inform them when requesting processing. Printing the photos can present problems, because modern film processing equipment often cannot handle the square format of 126 film. There are specialist photographic suppliers who can correctly process and print 126 film. Some standard flatbed scanners that have a light source for scanning films can be used to scan 126 negatives. All that may be required is a simple black mask, which can easily be made with black paper.[7]
