Silver salt photography

Japanese: 銀塩写真 - ぎんえんしゃしん(英語表記)silver salt photography
Silver salt photography
A general term for photography that uses silver salts such as silver halide, silver nitrate, silver azide, and silver tungstate as photosensitive materials. It began in 1727 when German Johann Heinrich Schulze (1687-1744) discovered the photosensitivity of silver nitrate. In 1839, Louis-Jacques-Mandé Daguerre invented the daguerreotype. Today, in contrast to digital photography using digital cameras, photographic film or photographs printed from film onto photographic paper are called silver halide photography (→printing).
