The cyanotype alternative photography process was invented in 1842 by Sir John Herschel. Sir John was an astronomer trying to find a way to copy his scientific notes. This technique is also known as the “blueprint” process used in architecture and construction. The photo that develops produces a permanent white image on a deep blue background. Cyanotype prints are made without the use of a camera.
The technique involves making a simple, light-sensitive solution which is painted onto sturdy paper and allowed to dry in the dark.
Objects are placed on the prepared paper and exposed to a UV light source. After exposure, the paper is rinsed and dried.
For my finishing touch, I sometimes use watercolor or diluted ink to tint a flower or leaf and then glue the print to a wood panel and coat it with several layers of encaustic wax medium.
