origin

First of all, the 35mm film means that the height of the film is 35mm, and the effective height is 24mm because there are perforations at the upper and lower ends. The photosensitive area of a single image of this film is 24 mm * 36 mm.

135 film uses 35mm film, and 35 is its height. So, what about the previous 1? The Leica camera designed by oskar barnack first used 35mm film, but at first, the film had to be put into the reusable contact, and the title had to be cut before shooting. 1934, Kodak introduced the disposable 135 film box, which was actually an invention of nagel camera factory in Stuttgart, Germany, and Kodak bought the factory. Kodak officially launched 1935 Kodak color film. So 1 of 135 refers to a disposable cassette different from a reusable cassette. The complete definition of 135 film is "35mm film with a disposable cassette".

There are two main specifications of 35mm black and white film: standard cassette 35mm film and disc 35mm film. The latter only needs to prepare a few empty cassettes to repackage themselves, so it is cheaper.
