Photochroms are mono photographs that have been given a degree of colourisation mechanically.
of the Aäc process
produces colourised images from a single black-and-white photographic negative via the direct photographic transfer of the negative onto lithographic printing plates.
The process was invented in the 1880s by Hans Jakob Schmid (1856–1924), who went on to found Zurich Photochroms, other companies to use the process were located in Detroit and London.
Because no colour information was preserved in the photographic process, the photographer would make detailed notes on the colours within the scene and use the notes to hand paint the negative before transferring the image through coloured gels onto the printing plates.
Most date around the 1890s and are considered to be in the public domain. There is a huge collection numbering some 6,500 images taken worldwide. I have enhanced and resized the images to the 3:2 ratio and increased the resolution so they may be standard prints, such as 6x4 or 7x5
