Cyanotypes

Cyanotypes are an old-fashioned photographic process. They are made by coating paper in a dark room with a light-sensitive chemical. The paper is left in the dark to dry. A photographic negative is then placed on top of the paper and sandwiched under glass to make perfect contact with the paper. The paper is then set in the sun and left to expose, usually about 5-10 minutes depending on the intensity of the sun. Once it has been exposed it is developed with water and it turns a beautiful blue color. Plants or objects can also be used instead of a photo negative.
