"These magnificent color postcards from the late 19th century depict the
breathtaking mountains, fjords, glaciers, and towns of Norway. The postcards
were created by the Detroit Publishing Company using the Photochrom process.
Photochrom produced colorized images from a single black-and-white photographic
negative via the direct photographic transfer of the negative onto lithographic
printing plates. The process is a photographic variant of chromolithography
(color lithography).
Because 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."
