8mm Collection
8 mm film exists in two main versions: the original standard 8mm film, and Super 8. Although both standard 8 mm and Super 8 are 8 mm wide, Super 8 has a larger image area because of its smaller and more widely-spaced perforations.
The standard 8 mm film format was developed by the Eastman Kodak company and released on the market in 1932 to create a home movie format that was less expensive than 16 mm.
In 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. Super-8 was at one point available with a magnetic sound track at the edge of the film but this only made up 5 to 8% of Super-8 sales and was discontinued in the 1990s.
