WHAT IS PHOTOCHROM(E)?
There were many ways of colorizing images before real color photography appeared by 1930. Among them, the Photochrom process stands out for its high quality. In 1900, The Detroit Publishing Co. called it ". . . the only successful means yet known of producing directly a photograph in the color of nature."
A Photochrom (photochrome) is a color photo lithograph, produced from a black-and-white negative. The final prints were created using different color impressions from multiple lithographic stones. The stones used were coated with a special Syrian 'asphaltum' substance that would be chemically sensitized to light, put in contact with a photographic negative, exposed to the sun for up to several hours, then "developed" in oils of turpentine.
The areas of the very thin asphalt gel most exposed to light would harden, becoming insoluble; the less exposed residue would be washed away. Tonal values of the remaining positive image could be manipulated by varying the chemistry and development times. Technicians could do the equivalent of burning and dodging by retouching the brush and polishing with fine pumice powder. The final steps in preparing the stone were an acid etch to bond the remaining image with its very fine grain, and a glycerin bath.
A separate stone would be made for each color to be used. A minimum of four stones and as many as fourteen stones might be used for a given image. A transparent ink would be applied to the stone, then transferred to high-quality paper whose texture resembled the smooth photographic printing paper of the day.
The final steps was a varnish which gave each print added depth and richness. Because the process involved a number of crafts people and because the stones had to be re-ground occassionally substantial variations may be noted between different editions of the same image over the years.
