When exposed to light, silver halide crystals form metallic silver that turns black when developed.  To make photographic film or paper, an emulsion of silver halide crystals in gelatin is coated on to a film base, paper or glass substrate.  A single ounce of silver can produce enough silver halides to take 5000 photographs.

A particular group of silver compounds known as silver halides are extensively used in the photography industry to make films for capturing images.  Silver halides are chemical compounds of silver with a halogen - typically bromine, chlorine and iodine - and they are the light sensitive ingredient used in photographic film.
