With this handy kit you can harness the power of the sun to make detailed prints from virtually any object that casts a shadow!

Cyanotypes are one of the oldest photographic printing processes in the history of photography. They are relatively easier to create as a dark room is not required, and it utilises the UV rays from the sun and iron salt solutions rather than silver salt solutions of early photographic processes. The image is first created by combining ferric ammonium citrate (Green) potassium ferricyanide to make an iron-rich sensitiser solution. The solution is then brushed evenly over paper or other porous surfaces. As the sensitiser chemicals react to light when exposed, the coating process takes place in dim light. These chemicals are then exposed to UV light such as sunlight, which creates ferric ferrocyanide, also known as Prussian Blue. The last step in the process is a water rinse to wash away the sensitiser solution, and the blue darkens as the print dries to reveal the final product.

This kit contains:

• 2 x  100ml bottles with the chemicals mixed.
• 1 x bottle of citric acid for the development.
• 3 x droppers for application.
• 1 x sponge brush for coating.
• 1 x instruction manual.
