COLOR PHOTOGRAPHY ON PAPER.

A. NEW PROCESS.

Dr J. H. Smith has invented a plioto- ! graphic printing paper capable of reproducing photographs in natural colors from suitable negatives. In his process a new paper called -"Utocolor" is placed upon the Autochrbme.or similar color plate in the printing: frame, and printed. in. the sim for about two hours, or longer in the shade,- just as any ordinary printing-out paper is employed. -The paper acquires the colors of the plate, and it is interesting to watch tlie evolution of the colors from the black surface of the .paper- direct in the printing frame without the application of any solutions •or developing agents. \ When the print; corresponds with the original it is taken out of the frame and fixed to ; render the dyes employed, morel permanent, then .finished, and mounted as an ' ordinary photograph. The resulting • print corresponds very closely with that of the original Autocliroine, all the line detail of light and shadow being, reproduced, in addition to a color rendering true to nature. <■■■:'

. The: colored prints obtained by this method have somewhat the appearance of; oil chromographs.The process therefore, appears particularly suitable for • the reproduction of oil paintings, or for the illustration of scientific papers accompanied by colored : plates containing a. variety of tints whicn render their exact reproduction by the ordinary means both difficult and costly. The colored reproduction, through a simple photographic printing frame, of transparent colored leaves, and other natural objects suggests a new :md delightful recreation for amateurs.
