Abstract
A method of measuring the light/time variations of flash light sources is described. A streak camera (after Brixner) has a neutral density step wedge over the slit. The light source to he recorded is arranged to illuminate the slit and step wedge uniformly at all points. Thus a number of light output/time records are produced simultaneously, the ratio of incident light to each record being known. Microdensitometer studies of these records are made from which logarithmic and linear graphs result. II & D curves of emulsion-developer combinations are also produced at submicro-second exposures. The advantage of logarithmic display is discussed.
