Silver bromide (AgBr), a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light. This property has allowed silver halides to become the basis of modern photographic materials.^[2] AgBr is widely used in photographic films and is believed by some to have been used for making the Shroud of Turin.^[3] The salt can be found naturally as the mineral bromargyrite (bromyrite).
