Griffithsia corallina 1851 - 1855

Anna Atkins's *Griffithsia corallina* is a cyanotype, a photographic process that uses a light-sensitive iron solution to create a blue-toned print. Made between 1851 and 1855, the image is part of Atkins's *Photographs of British Algae: Cyanotype Impressions*. This groundbreaking work was the first book illustrated entirely with photographs, documenting the beauty and complexity of seaweed. This particular print showcases a delicate specimen of *Griffithsia corallina*, its intricate branches rendered in striking white against the deep blue background, highlighting the intricate details of the algae.
