Cyanotype

Trained as a botanist, Anna Atkins developed an interest in photography as a means of recording botanical specimens for a scientific reference book, British Algae: Cyanotype Impressions. This publication was one of the first uses of light-sensitive materials to illustrate a book. Instead of traditional letterpress printing, the book’s handwritten text and illustrations were created by the cyanotype method. Atkins printed and published Part I of British Algae in 1843 and in doing so established photography as an accurate medium for scientific illustration.
