Gum Bichromate - a process from the 1890's, which involves coating a paper with watercolour pigment and gum arabic, mixed with a sensitizer. The print is developed in water and a brush is often used to lighten areas, creating the characteristic painted feel.
Cyanotype - a process discovered by Sir John Herschel in 1842. Ammonium iron citrate and Potassium ferricyanide are dissolved in water and coated on paper, usually using a brush. A contact print is made by placing a negative onto the paper and exposing it to ultraviolet light. The picture is developed by flushing it with flowing water.
Kallitype - the paper is coated very much in the same way as in the Cyanotype process, but with a solution of ferric oxalate and silver nitrate. It is also a contact-printing process and usually produces a very rich brown print. Another process from the 1890's, it is close cousin of platinum and palladium printing.
