I think it would be bromide(Silver Bromide) because Silver Bromide was used in films for cameras before they all became digital cameras.
The "salt" you are referring to is actually called silver-halide and are more commonly known as "silver salts". When silver-halide crystals are exposed to light, they form a compound known as "metallic silver"
The product is a silver halide insoluble in water.
Silver chloride, bromide or iodide (photosensitive compounds)
Silver oxide is photosensitive and silver can be separated.
Silver halides contain the metal (Ag, silver) and a halogen: F, Cl, I, Br.
an emulsion of small particles of a photosensitive silver salt (Usually silver halide) suspended in gelatin
To form an insoluble silver halide.
The part of the silver halide crystal that is most affected by light when film is exposed is the surface. More specifically, any sensitivity specks that can become metallic silver.

The larger the silver halide crystals are, the higher the films speed rating will be. The film will also be easier to overexpose.
The presence of halide ions
Silver Halide Silver iodide
Silver salts (AgCl)
A silver salt, more specifically a silver halide.
silver bromide
Silver chloride, bromide or iodide (photosensitive compounds)
