The images in this gallery consist of alternative and historic photographic processes.

The first group consists of photograms, chemogram and lumen prints which are unique cameraless images. The photogram dates back to the origins of photography.

Cyanotype, distinguished by its vivid blue color, was the first successful non-silver photographic printing process. Sir John Herschel invented it as well as the brown colored Van Dyke or Kallitype process in 1842.

The process known as albumen was introduced by Blaquart-Evard in 1850. Its color is yellow-brown to red-brown and it uses paper coated with egg whites.

Salt prints are also brown and are a process using salt and silver nitrate.
