Photochrom Prints of Canada and USA

Photochrom prints of Canada and the United States of America (USA) from the 1890s and early 1900s.

Photochrom (also fotochrom or photochrome) is a process for producing colorized images from a single black-and-white photographic negative via the direct photographic transfer of the negative onto lithographic printing plates. Since no color information was preserved in the photographic process, the photographer would make detailed notes on the colors within the scene and use the notes to hand-paint the negative before transferring the image through colored gels onto the printing plates.
