The Cyanotype, which is also known as ferroprussiate or blueprint was invented by Sir John Herschel in 1842, when he discovered that ferric (iron) salts could be reduced to a ferrous state by light and then combined with other salts to create a blue-and-white image. Not long after, Anna Atkins, one of the few women in photography during that century, published the first book with photographs instead of illustrations, "British Algae: Cyanotype Impressions"

Cyanotypes are a photographic process where paper or fabric is coated with a light-sensitive emulsion. The closest to the darkroom that digital photography students will experience, this old process is making a comeback.

In this PBL lesson, students will explore the chemical process of building an image with digital film.

This project is brought to you by Gayle Nicholls-Ali with support from the CTE Online curriculum leadership team.
