135 film

Generally, the film base thickness of 135 film is .135mm.. 135 film originated from 35mm perforated cinematographic film. In 1913, oskar barnack, a German, used it in his Leica brand small camera, thus forming the standard.

Japanese industrial standard for 35mm film. Such as 135-36, 135-2, etc., refers to the number of frames taken by a film.

Origin

First of all, 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 24mm*36mm.

135 film is made of 35mm film, and 35 is its height. So, what about the front 1? The Leica camera designed by Oscar Barnack first uses 35mm film, but at first, the film must be put into a reusable contact, and the title is cut before shooting. In 1934, Kodak introduced a disposable 135 film box, which was actually an invention of Nagel camera factory in Stuttgart, Germany, and Kodak bought the factory. Kodak officially launched 135 Kodak color film in 1935. Therefore, the 1 of 135 refers to a disposable cassette different from a reusable cassette, and the complete definition of 135 film is "35mm film using disposable cassette".

The common 35mm black-and-white film mainly has two specifications: the standard cassette 35mm film and the disc loaded 35mm film. The latter can be repackaged by itself only by preparing several empty cassettes, so it is cheaper.
