Standard 8 mm film
Standard 8 mm film (also known as Regular 8 mm, Double 8 mm, Double Regular 8 mm film, or simply as Standard 8 or Regular 8), is an 8 mm film format originally developed by the Eastman Kodak company, and released onto the market in 1932. In the 8 mm system, the photographic film is manufactured as 16 mm film on a spool for use in a home movie camera. The film then gets exposed on one half of the film, the operator flips the spool, and then the opposite half of the film gets exposed in the reverse direction. The exposed film is then processed, slit down the middle, spliced together, and finally wound onto a spool for viewing on an 8 mm film projector.
8 mm cameras and projectors were originally designed for 16 frames per second, but this was later changed by some manufacturers to higher speeds to reduce flickering. Most cameras designed for 8 mm film were made with consumers in mind. Typical features include spring-wound operation, lightweight camera bodies, small viewfinders, and single, fixed lenses. Only brief scenes could be filmed without pausing to rewind the spring or flip the film spool. During loading, the film has to be manually handled to guide it into a camera's film gate and onto a take-up spool, best done in a darkened area.
Standard 8 mm film cameras and projectors were prominent from the 1930s to 1970s, after which the system became obsolete in all but niche uses. The introduction of the cartridge-based Super 8 mm film in 1965 offered consumers better quality and convenience, leading to a decline of Standard 8 mm use.
The format, initially known as Cine Kodak Eight, was developed by Kodak to provide a cheaper and more portable alternative to the 16 mm film format introduced a decade earlier. Kodak also introduced a line of Ciné-Kodak Eight cameras using the new format.
The format was an immediate success, but retains a number of inherent problems and quirks, mostly connected with the fact that the spool needs to be removed and reversed halfway through filming. This procedure is tricky for the inexperienced user and needs to be carried out in subdued light to avoid fogging of the edges of the film. In addition, the central six feet of the finished film includes a characteristic burst of light corresponding to the reversal point (unless the film is again edited and spliced).
The standard spool size for amateur use contains 25 ft of film, giving a total of 50 ft available for projection; at the usual filming speed of 16 frames per second this gives about four minutes of footage. In the early 1960s, a new filming and projection standard of 18 frames per second was introduced, and films with sound increased the speed again to 24 frames per second; many cameras and projectors include a multi-speed facility.
The standard 8 mm format was displaced by the Super 8 mm film format, which offers cartridge loading, a 50% larger frame size and electric-powered cameras starting from the latter format's introduction in 1965. Super 8 was criticized because the film gates in some cheaper Super 8 cameras were plastic, as was the pressure plate built into the cartridge; while the standard 8 cameras had a permanent metal film gate that was regarded as more reliable in keeping the film flat and the image in focus. In reality, this was not the case, since the plastic pressure plate could be moulded to far smaller tolerances than their metal counterparts could be machined. Another criticism of Super 8 was that more sophisticated standard 8 mm cameras permit backwind of the film – difficult but not impossible with a Super 8 cartridge – enabling simple double-exposure and dissolve effects to be made in-camera. Finally, Super 8's smaller sprocket holes, while allowing a larger frame size, were also inherently more liable to tear.
Although standard 8 mm was originally intended as a format for creating amateur films, condensed versions of popular cinema releases were available on the format up until the 1970s, for projection at home. These were generally edited to fit onto a 200 ft reel. Many Charlie Chaplin films, and other silent movies were available. Short, silent versions of sound films with dialogue titles added were also released, including W. C. Fields' The Bank Dick, which emphasized the chase sequence at the end of the movie. Also available were newsreels covering the previous year and short versions of sound cartoons. Castle Films was the major supplier of these films. The Walt Disney Studio released excerpts from many of their animated feature films, as well as some shorts, in both Standard and Super 8, some even with magnetic sound. New releases of material continued until the late 1970s in the US.
