Ceramium diaphanum 1851 - 1855

"Ceramium diaphanum" is a cyanotype photograph from Anna Atkins's groundbreaking book "Photographs of British Algae: Cyanotype Impressions". This image is a single page from the book and depicts a delicate specimen of red algae, a type of seaweed, against a vibrant blue background. Atkins, a pioneering photographer and botanist, used the cyanotype process to create these photograms, capturing the intricate details of marine flora. Her work paved the way for the use of photography as a scientific tool, specifically in the field of botany.
