In 1965, the original emulsion released was II colour film. However in 2005, Kodak announced it would stop manufacturing Kodachrome stock. The discontinuation was due to the steps used. Nowadays, Kodak Super 8mm film cartridges are sold as either colour reversal film, black and white reversal film or colour negative film (in 200 and 500 ISO speeds). Fuji Velvia 50 and a number of other stocks are also available.
Before Kodak introduced Super 8 film, making home movies was a pain. People first had to thread old-fashioned 16 mm film into a camera by hand and, on its first pass through the camera, the film was exposed along only half of its width. The camera then had to be opened and the spools flipped so that the unexposed edge of the film could be recorded on during the film's second pass through the camera. After the film was processed, it was slit in half, lengthwise, in order to make two lengths of 8 mm film to fit into a projector.
During CES 2016 Kodak has unveiled a new Super 8 prototype camera that it hopes will bring a revival to the Kodak Super 8 film which is celebrating 50 years of manufacturing this year.
Super 8 didn't have any of those hassles and provided great image quality, revolutionizing the amateur film genre in the process. Kodak launched Super 8 mm film in May 1965, along with two cameras, the M2 and M4. Super 8 was cheaper and more convenient than the previous, cumbersome Normal 8 format, since all you had to do was pop the film cassette into the camera, take it out after and turn it in for processing.
