Category:Photochrom pictures
Photochrom prints are colorized images produced from black and white photographic negatives via the direct photographic transfer of a negative onto lithographic printing plates. Photochromes have a very sharp image, have natural and realistic colours, and at the bottom they have a serial number and a caption in capital letters. If not, then it is only a hand-colored photograph, not a photochrom.
This process (also called the “Aäc process”) is properly considered a photographic variant of chromolithography, a broader term referring to color lithography in general.
