Bunsen-Roscoe law

Definition: Amount of chemical change produced is proportional to the amount of light absorbed. * Applied to photography, the amount of light-induced chemical change is proportional to the amount of actinic light adsorbed. * In fact, this 'law' is inaccurate: the amount of change also depends on the intensity of light.
