Cyanotype photography was invented in 1842 by Sir John Herschel, a British scientist.
They are often called “sun prints” because they are developed using sunlight.

Cyanotypes were originally used for reproducing architectural and engineering drawings, giving rise to the term “blueprint.”
The process to make Cyanotypes involves two simple chemicals: ferric ammonium citrate and potassium ferricyanide, which react to produce the cyan-blue color when exposed to UV light.
Cyanotype prints can be made on different surfaces such as paper, fabric, ceramics or even ai art, offering a versatile medium for artistic expression.
