(written by notion AI) 135 film, also known as 35mm film, is a type of photographic film that is widely used in the film industry. It was introduced by Kodak in 1934 and has since become one of the most popular film formats for still photography and motion pictures. The film is made up of a strip of plastic that is coated with an emulsion of silver halide crystals. The film is usually sold in rolls and is loaded into a camera for use. The film can be used to take both black and white and color photographs.

• slow film = relatively insensitive film
• fast film = highly sensitive film

<aside> ❓ Q: slow film + high exposure = fast film + low exposure ??? A: ****no! fast film (highly sensitive film) tends to be a lot more grainy.

• Warnerke
• DIN system (DIN standard 4512) (1961–2002): logarithmic scale
