Cyanotypes -
A cyanotype is almost like a photographic blue print. It is a cyan (cyan-otype) coloured.
Cyanotypes is a process used in Photography.
The most famous user of this is Anna Atkins in a 12 part book named 'British Algea: Cyanotypes'.
Cyanotypes were one of the first kinds of photographs that did not require a camera. This technique reflected this, ‘photography’ - photo is light; graph is to draw. This means, photography is drawing with light.
Atkins was an a Botanist and Illustrator of plants, she discovered the technique Cyanotypes after meeting British inventor Fox Talbot who told her about the technique. Her neighbour also found out that exposing soaked paper (soaked in Iron Salt) and expose it to U.V light made a negative image.
The cyanotype process is quite cheap and really easy to use, and you don't need a darkroom or any complicated equipment.
However some disadvantages consist of that you cannot have any colour on the image and they can only have shades of blue e.g Dark Blue, Light Blue.
Potassium ferricyanide and Ferric ammonium citrate (green) are mixed with water separately. The two solutions are then blended together in equal parts, and then the paper is soaked in this solution and exposed to a U.V lights e.g the Sun.
