Benzotriazole in a photographic developer has been determined to increase covering power. This is accompanied by a decrease in photographic speed proportional to the increase in covering power. Benzotriazole decreases the rate of development when measured by mass of silver developed, but may increase the rate of development when measured by density at D-max exposures because of the increase in covering power. The effect of benzotriazole on image color has also been determined. Possible explanations for effects are given.
