Cellulose nitrate (c. 1889 – c. 1950) is the first of film supports.It can be found as roll film, motion picture film, and sheet film. It is difficult to determine the dates when all nitrate film was discontinued, however, Eastman Kodak last manufactured nitrate film in 1951. [1]
Cellulose triacetate superseded nitrate as the film industry's mainstay base very quickly. While Kodak had discontinued some nitrate film stocks earlier, it stopped producing various nitrate roll films in 1950 and ceased production of nitrate 35 mm motion picture film in 1951. [49]
Despite the dangers of the nitrate film base being known practically since its development, it was used in virtually all major motion pictures prior to 1952, when Kodak completed a four-year conversion program to the sole manufacturing of acetate base film stocks. Kodak began working with acetate "safety film" as early as 1909, and started ...
All amateur film stocks were safety film, but the use of nitrate persisted for professional releases. Kodak discontinued the manufacture of nitrate base in 1951, and the industry transitioned entirely to safety film in 1951 in the United States and by 1955 internationally.

1889: Film negatives Cellulose nitrate film was developed by Eastman Kodak in 1889 and refined in 1903. It is made of silver gelatin on a cellulose nitrate base. The negatives are flammable and therefore can be dangerous. Nitrate sheet film was used widely though the 1930s, while nitrate roll film was used through the 1950s.
The "serpentine" and "stone" of the pillars are made of celluloid glued to wood. Assorted tortoiseshell celluloid guitar picks. Most movie and photography films prior to the widespread move to acetate films in the 1950s were made of celluloid. Its high flammability was legendary since it self-ignites when exposed to temperatures over 150 °C in ...
A Nitrate Film Preservation Facility on the Communications Research Centre campus in Shirleys Bay, on the outskirts of Ottawa, houses Canada's cellulose nitrate film collection. [71] The collection contains 5,575 film reels dating back to 1912, including some of the first Canadian motion pictures and photographic negatives.
