  • The Chemistry of Photography

    As chemical information has been developed over time, the photographic process has been refined and optimized to the point where these early discoveries are often taken for granted The chemistry of photography is based on photosensitivity and reactions with light The chemical processes that create a traditional photograph start inside the cameraPhotochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light The consequence of molecules’ absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules These new chemicalPhotochemical reaction | chemical reaction | Britannica
