Cyanotype
Cyanotype is a traditional photographic printing process developed in the mid-18th century and is distinctive for its rich blue color. How it works: When cyanotype-soaked paper is exposed to sunlight, a chemical reaction occurs. However, it won’t show up until you put the paper in water. Then it immediately turns blue!
