[A] Ulva crispa / [B] [Ulva] Furfuracea / [C] [Ulva] Calophylla c. 1843 - 1853

This cyanotype print, created by Anna Atkins between 1843 and 1853, depicts three different species of seaweed: *Ulva crispa*, *Ulva furfuracea*, and *Ulva calophylla*. Atkins, a pioneering photographer, used the cyanotype process, a photographic printing technique that produces a blue-toned image, to document her botanical studies. This specific print, part of her groundbreaking book "Photographs of British Algae: Cyanotype Impressions", showcases the intricate details and textures of seaweed, highlighting Atkins' contribution to the field of scientific illustration.
