The use of simultaneous pulses of light and voltage to study the motion of electrons and holes in photographic grains and the role played by these charge carriers in the formation of the latent image is discussed. The electric field displacement of conduction electrons forming print‐out as well as latent‐image silver is shown by electron micrographs of the grains. Also, results on the motion of positive holes are presented. It is possible to show at the print‐out level that this carrier is mobile; although it may be that the hole is displaced at the latent‐image level, this behavior has not been demonstrated. The light and voltage pulses used for the exposures are analyzed and related to electron displacement. Indications are that when electrons are forced to the grain surface by an electric field, they are trapped in a time less than 1 μsec.
