The inventor of the 35mm roll-film camera was Oscar Barnack
Traditional still-Photography developed in the 19th century using large, cumbersome cameras and photographic plates. In the early 20th Century Oskar Barnack, an engineer at the German company Leitz, which made precision optical instruments such as microscopes, and who was a keen amateur photographer decided to do something about the size of the cameras. This was to a large part due to his physical frailty (he suffered badly from Asthma and found it difficult lugging the heavy photographic equipment about). He began experimenting with with cinematic film and a light meter which he adapted and improved.
At the time cinema cameras shot on 35mm film with a frame size of 18x24mm. Barnack found that this format produced poor quality still photographs and he doubled the frame size to 24x36mm. Originally the film was supplied on large reels (known as a roll) and had to be cut into manageable lengths and placed in the camera in absolute darkness but as the popularity of the format increased, re-loadable film cartridges were developed and eventually companies such as Agfa and Kodak began supplying the film to photographers in single-use cartridges.
With the development of the film cartridge the phrase 'roll of film' migrated to mean a cartridge of 35mm film. Over the years other formats and systems were spawned including medium format roll-film, 110 cartridge, Minox miniature format, APX and disk but thanks to the vision of Oskar Barnack and the versatility of the format he created the humble 35mm roll of film is the only one to stand the test of time.
Yes, Expired film is still processable. I just took pictures with an expired 35mm disposable camera that expired in 2002... and the pictures came out! The colors were not as vibrant as they would have been with new film, but not so bad for 7 year old film. If I wasn't comparing the pictures with a new roll of film, you wouldn't notice the difference.
It was invented in 1957 by André Cassagnes, a French electrician. He took the idea to a plastics company; they developed a prototype and patented it in 1959 and did not give him credit on the patent. Ohio Art Company bought a license to make the toy in the US and announced the Etch-A-Sketch in July, 1960.It was invented on July 12,1960.
it was invented in 1902
For cameras, about 1902. Production of the patent from that year did not take place until about 1932 and was used in 35mm movie cameras as the first true zoom (meaning the focal plane did not shift appreciably when the lens was zoomed). The concept was first invented for telescopes around 1834, but it was a varifocal lens, in that it did not maintain focus when zoomed).
