Silver, nitric acid, and gelatin
- A roll of film consists of the emulsion and base that compose the film itself, the cassette or cartridge, and outer protective packaging. The materials used to make the emulsion are silver, nitric acid, and gelatin. The base consists of cellulose and solvents that are mixed to form a thick fluid called dope.

Photographic emulsion is a fine suspension of insoluble light-sensitive crystals in a colloid sol, usually consisting of gelatin. The light-sensitive component is one or a mixture of silver halides: silver bromide, chloride and iodide.
Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film. [1] Film is typically segmented in frames, that ...
Sep 21, 2023 · The film we load into our cameras is made of two main parts: The emulsion and the base. The base is usually made of cellulose triacetate, acetate, or polyester. It's a synthetic support that hosts and binds the emulsion. It is designed to endure winding and re-winding in the camera.
Film is composed by two main parts, the base and the emulsion. The film base is usually made of cellulose triacetate, acetate, or polyester. The emulsion is the active ingredient that will capture the final image.
photographic emulsion. The light-sensitive coating given to photographic materials. It consists of crystals (usually called grains) of silver halides, suspended in gelatin which is coated on to a base of glass or film.
Photographic emulsion is an indispensable element for photography. A chemical gel in photographic emulsion enhances the coating formation on the photographic paper. Gelatin and collagen are widely used as photographic emulsion due to their chemical composition and chemical structure. Read more.
