Due to its light sensitive nature, the main applications of silver bromide are in photography. It is used in photographic films and plates. It is also used for infrared applications, for light sensitive eyeglasses, and semiconductors
Silver bromide is photosensitive. Due to its light sensitivity, when silver bromide is suspended into gelatin, silver bromide creates a photographic emulsion. So, Silver bromide is used in photography because when it is exposed to sunlight it decomposes and is converted into metallic silver grains
