Cyanotypes
The cyanotype process is a simple, light-sensitive printing method that produces a characteristic Prussian blue image. It involves coating paper with a solution of iron salts and potassium ferricyanide, then exposing it to UV light. Unexposed areas remain blue, while areas exposed to light turn white, creating a blue-and-white image.
Both these images were shot digitally on a Canon and printed using the Cyanotype process.
Albumen Prints
The albumen process, a popular photographic printing process of the 19th century, involved coating paper with a mixture of egg white (albumen) and salt, then coating it with a silver nitrate solution to create light-sensitive silver salts. The sensitized paper was then exposed to light in contact with a negative, producing a positive image. After exposure, the print was rinsed, toned (often with gold or selenium), fixed, and washed.
The images are from my personal archives and were taken throughout Egypt in 2009.
