Standard 8The standard 8 mm film format was developed by the Eastman Kodak company during the Great Depression and released on the market in 1932 to create a home movie format less expensive than 16 mm. The film spools actually contain a 16 mm film with twice as many perforations along each edge than normal 16 mm film, which is only exposed along half of its width. When the film reaches its end in the takeup spool, the camera is opened and the spools in the camera are flipped and swapped (the design of the spool hole ensures that this happens properly) and the same film is exposed along the side of the film left unexposed on the first loading. During processing, the film is split down the middle, resulting in two lengths of 8 mm film, each with a single row of perforations along one edge, so fitting four times as many frames in the same amount of 16 mm film. Because the spool was reversed after filming on one side to allow filming on the other side the format was sometime called Double 8. The framesize of 8 mm is 4,8 x 3,5 mm and 1 m film contains 264 pictures. Normally Double8 is filmed at 16 frame/s. Common length film spools allowed to film about 3 to 4 min at 12, 15, 16 and 18 frames per second. Kodak ceased producing standard 8 mm film in the early 1990s. Black and white 8 mm film is still manufactured in the Czech Republic, and several companies buy bulk quantities of 16 mm film to make regular 8 mm by re-perforating the stock, cutting it into 25 foot (7.6 m) lengths, and collecting it into special standard 8 mm spools which they then sell. Re-perforation requires special equipment. Some specialists also produce super 8 mm film from exisiting 16 mm, or even 35 mm film stock. Super 8In 1965, Super-8 film was released and was quickly adopted by the amateur film-maker. It featured a better quality image, and was easier to use mainly due to a cartridge-loading system which did not require re-loading halfway through. Sometimes, the improvement was not as apparent, since the film gate in some cheap Super 8 cameras were plastic as was the pressure plate, which was built in to the cartridge, whereas the standard 8 cameras had a permanent metal film gate that better kept the image in focus. There was another version of Super-8 film, Single-8, produced by Fuji in Japan. It has the same final film dimensions, but the cassette is different. The Kodak system was by far the most popular.
