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]
Nitrate film stock was used in every major film production before about 1951. Many silent films only survived because they were printed to 16 mm film , which did not use a nitrate base. A report published by the United States Library of Congress in September 2013 states that 70 percent of all American silent feature films are lost.
Cellulose triacetate superseded nitrate as the film industry's mainstay base very quickly.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]
Adox was a German camera and film brand of Fotowerke Dr. C. Schleussner GmbH of Frankfurt am Main, the world's first photographic materials manufacturer. In the 1950s it launched its revolutionary thin layer sharp black and white kb 14 and 17 films, referred to by US distributors as the 'German wonder film'. [1]
Although a very early pioneer in trichromatic color film (as early as 1908), invented by German chemists Rudolf Fischer and Benno Homolka [], Agfa film was first made commercially available in 1936 (16 mm reversal and 35 mm), [2] Agfa-Gevaert has discontinued their line of motion picture camera films.
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. Since the late 1990s, almost all release prints have used polyester film stock.
By 1911, the major American film studios had reverted to nitrate stock. [12] "Safety film" was relegated to sub-35 mm formats such as 16 mm and 8 mm until improvements were made in the late 1940s. Nitrate film is also chemically unstable and over time can decay into a sticky mass or a powder akin to gunpowder. This process can be very ...
Nitrate sheet film was used widely though the 1930s, while nitrate roll film was used through the 1950s. The nitrate base was replaced with cellulose acetate in 1923. By 1937, Cellulose diacetate was used as the base, and beginning in 1947 Cellulose triacetate was used. [6] Polyester film was introduced around 1960. [7] 1935: Color photographs
