A study of certain chemical baths and combinations of chemical baths was made to determine their effect on the print-out image of a specially-prepared conventional developing-out enlarging paper. These Print-out images were formed and made visible entirely from the photolytic effect of the image exposure. Arc lamp, tungsten lamp and electronic flash lamp exposures were made; arc lamp exposures were the most satisfactory. The chemical associated with the most image improvement was stannous chloride.
