Zygnema nitidum c. 1843 - 1853

"Zygnema nitidum" is a cyanotype print from Anna Atkins’ groundbreaking book "Photographs of British Algae: Cyanotype Impressions". Atkins, a pioneer in the field of photography, used the cyanotype process, which she helped popularize, to capture intricate details of algae specimens. This particular print, dating back to the mid-19th century, showcases the delicate, thread-like structure of the Zygnema nitidum algae, a type of green algae found in freshwater environments.
