By using silver bromide microcrystals obtained from a high sensitive photographic film emulsion, the effects of the intensity of light source and the temperature of t1?e specimen on the print-out effect of the silver bromide crystals were studied electron-microscopically. As a result, it was found that with increasing the intensity of light source or with raising the temperature of the specimen the density of the pits decreased and well-defined tri-pyramidal pits began to appear on the surface of the grain. Although triangular patterns were observed frequently on the surface of the grain at room temperature for weak light illumination, they decreased in number and became large in size with increasing the intensity of light source or with raising the temperature of the specimen. The protrusion and whisker of silver also appeared on the grain at an elevated temperature due to light illumination. Experimental results obtained are discussed.
