Chemistry in Photography Background A photograph is an image made by a photo-chemical reaction which records the impression of light on a surface coated with silver atoms. The reaction is possible due to the light-sensitive properties of silver halide crystals. Equation form for silver halides: Ag + + e - Ag Species produced include: Ag2+‚ Ag2o‚ Ag3+‚ Ag3o‚ Ag4+‚ Ag4o In 1556‚ the alchemist Fabricius was the first to discover that light can photochemically react with these crystals to
