First Impressions

These images were created using the cyanotype process, which was discovered by the English scientist and astronomer Sir John Herschel in 1842. I painted cotton fiber paper with a liquid emulsion comprised of ammonium iron citrate, potassium ferricyanide, and distilled water. After the painted paper dried, objects were placed on top of the paper and exposed to the sun for a period of time. After exposure to the sun, the paper was rinsed in water and the final image appeared.
