Cyanotype

Cyanotype is a photographic form of printmaking that produces cyan-blue prints. It involves treating paper or fabric with a light-sensitive solution containing iron compounds. Objects or negatives are placed on the treated surface and exposed to UV light, typically sunlight. Where the light hits the surface, the iron compounds undergo a chemical reaction, forming a blue-colored compound called Prussian blue. After exposure, the material is rinsed in water to halt the reaction and fix the image. The result is a distinctive blue print with a silhouette-like quality, often used for creating photograms or making prints from objects like leaves or flowers. Cyanotype is celebrated for its simplicity, low cost, and unique aesthetic, making it a popular choice among artists and photographers for the creation of striking, cyan-blue images.
