Cystoseira barbata 1851 - 1855

Anna Atkins, a pioneer in photography, created "Cystoseira barbata" as part of her groundbreaking book *Photographs of British Algae: Cyanotype Impressions*. The cyanotype process, which she helped popularize, uses sunlight to create a blue-toned image on paper. This example from 1851-1855 is a testament to Atkins's meticulous documentation of the natural world, using photography to capture the intricate details of seaweed specimens.
