Definition

Noun: * A light-sensitive material used in photography: Photographic film is a flexible strip or sheet, typically made of a plastic base (like celluloid or polyester) coated with a layer of emulsion containing light-sensitive silver halide crystals. It is used in cameras to record a latent image when exposed to light, which is then made visible through chemical development to produce a negative or a transparency (slide).

Usage

• General Use: The term refers to the physical medium used in analog (film) photography.
  • I need to buy a roll of photographic film for my vintage camera.
  • The quality of the image depends greatly on the type of photographic film used.
• Technical/Descriptive Use: Used to specify the material in technical contexts or to distinguish it from digital sensors.
  • The archive contains thousands of feet of historical photographic film.
  • Unlike digital sensors, photographic film has a characteristic grain structure.

Advanced Usage

• "to be on film": to have been recorded using photographic film.
  • The historic moon landing was captured on film.
• "film speed" (ISO/ASA): a measurement of a photographic film's sensitivity to light.
