Silver bromide (AgBr) is a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light.[6] This property has allowed silver halides to become the basis of modern photographic materials.[7] AgBr is widely used in photographic films and is believed by some to have been used for making the Shroud of Turin.[8] The salt can be found naturally as the mineral bromargyrite.[9]
