Wet Plate Collodion Print
The wet plate collodion print process was originally introduced by Englishman Frederick Scott Archer in 1851. He used soluble iodide and mixed it with cellulose nitrate. This solution was painted onto a piece of glass and then was immersed in silver nitrate to form silver iodide. A few other solutions were added to create an image as shown above. The process now varies, and it can even be reproduced digitally.
Cyanotype
The cyanotype process was first introduced by Sir John Herschel in 1842, but since then, many artists have reproduced this process in diverse manners. Today, the cyanotype process can be reproduced through a digital process. Originally, cyanotypes where created by mixing Potassium ferricyanide and Ferric ammonium citrate. Cyanotypes are always a shade of blue, and part of the original image is covered by this blue color.
Gum Bichromate
The gum bichromate process involves using a sort of dichromate, pigment, and gum arabic. This process is often produced on paper or glass. A gum bichromate print can have many take many forms and have many various colors, depending on the pigment used. Fox Talbot is best known for his gum bichromate process.
