Cosina Super 8 (movie film camera)

Super 8 camera history
Launched in 1965, Super-8 film comes in plastic light-proof cartridges containing coaxial supply and take-up spools loaded with 50 feet of film. This was enough film for 2.5 minutes at the U.S. motion picture professional standard of 24 frames per second, and for 3 minutes and 20 seconds of continuous filming at 18 frames per second (upgraded from Standard 8 mm's 16 frame/s) for amateur use, for a total of approximately 3,600 frames per film cartridge. A 200-foot cartridge later became available which could be used in specifically designed cameras, but that Kodak cartridge is no longer produced. Super 8 film was typically a reversal stock. In the 1990s Pro-8 mm pioneered custom loading of several Super-8 stocks. Today Super 8 color negative film is available directly from Kodak for professional use and is typically transferred to video through the Telecine process for use in Television advertisement, music videos and other film projects.
The Super-8 plastic cartridge is probably the fastest loading film system ever developed as it can be loaded into the Super-8 camera in less than two seconds without the need to directly thread or even touch the film. In addition, coded notches cut into the Super-8 film cartridge exterior allowed the camera to recognize the film speed automatically. Not all cameras can read all the notches correctly though and not all cartridges are notched correctly such as Kodak Vision2 200T. Usually, testing one cartridge of film can help handle any uncertainty a filmmaker may have about how well their Super-8 camera reads different film stocks. Color stocks were generally available only in tungsten (3400K), and almost all Super 8 cameras come with a switchable daylight filter built in, allowing for both indoor and outdoor shooting.
The original Super-8 film release was a silent system only, but in 1973 a sound on film version was released. The sound film had a magnetic soundtrack and came in larger cartridges than the original so as to accommodate a longer film path (required for smoothing the film movement before it reached the recording head), and a second aperture for the recording head. Sound cameras were compatible with silent cartridges, but not vice versa. Sound film was typically filmed at a speed of 18 or 24 frames per second. Kodak discontinued the production of Super 8 sound film in 1997, citing environmental regulations as the reason (the adhesive used to bond the magnetic track to the film was environmentally hazardous).
Kodak still manufactures several color and black-and-white Super 8 reversal film stocks, but in 2005 announced the discontinuation of the most popular stock Kodachrome [2] due to the decline of facilities equipped with the equipment for the K-14 process. Kodachrome was "replaced" by a new ISO 64 Ektachrome, which used the simpler E-6 process There were only two Kodachrome labs in the entire world whereas now, all Super-8 film stocks, from color and black and white reversal, to color negative, can be processed same day in several labs around the world.
Kodak has also introduced several Super 8 negative stocks cut from their Vision film series, ISO 200 and ISO 500 which can be used in very low light. Kodak reformulated the emulsions for the B&W reversal stocks Plus-X (ISO 100) and Tri-X (ISO 200), in order to give them more sharpness. Many updates of film stocks are in response to the improvement of digital video technology. The growing popularity and availability of non-linear editing systems has allowed film-makers to shoot Super-8 film but edit on video, thereby avoiding much of the scratches and dust that can accrue when editing the actual film. Super-8 Films may be transferred through telecine to video and then imported into computer-based editing systems. Along with the computer editing option a number of enthusiasts still choose to edit super 8 film with a viewer and rewinds and then project their edit master on a film projector and movie screen.
