Latent image

The emulsion layer consists of silver halide crystals where silver bromide (AgBr) is the most common type of crystal at 95% while silver iodide is at 5% ⁶. The silver iodide ions functioned to introduce defect within the silver bromide crystal because a perfect crystal does not have photographic sensitivity. A sensitivity speck is introduced into the silver halide crystal by silver sulfide in order to trap electrons. When exposed to light or X-rays, a bromide ion releases an electron that is attracted to a sensitivity speck. In this process, the bromide ion becomes a bromine atom and diffuses into the gelatin. The electron gets attached to the sensitivity speck and attracts a silver ion. The silver ion attaches to the sensitivity speck and forms a silver atom. The silver atom continues to attract other silver ions to form more silver atoms. At least two to six silver atoms are required for a latent image to be processed into a visible image. During film processing, more silver atoms are produced, thus metallic silver (black) image is formed ^1,2.

Silver halide crystals are inherently sensitive to blue and ultraviolet light. Only with the addition of dyes, then the crystals can become more sensitive to other spectrums of light such as green and red ³.
