What is Cyanotype?

Cyanotype Printing, this technique, which dates back nearly 200 years, was the first-ever method for creating images with light-sensitive chemicals.

Historical Background

This printing process was invented in 1842 by Sir John F. W. Herschel. It was used for reproducing technical drawings, known as blueprints. It was consider an ingenious way for reproducing images and drawings using a negative for its time. Cyanotype photographic printing technique became on of the oldest processes in the history of photography.

Cyanotype was a term coined because of its cyan-blue color, in modern time it was referred to as Persian Blue. Later on it gathered recognition for its unique deep blue high contrasty look and for its indestructible prints.

The Process

Cyanotype printing is like painting with sunlight. A mixture of light sensitive chemicals is applied to paper or fabric, making it sensitive to light. After placing objects or images on the surface, sunlight is used to expose the design, turning it into beautiful shades of deep blue. Once it is washed in water, the hidden image is revealed, creating a unique artwork shaped by light and time.
