Halyseris polypodioides c. 1843 - 1853

This cyanotype photograph, titled *Halyseris polypodioides*, was created by Anna Atkins between 1843 and 1853. Atkins is known for her pioneering use of the cyanotype process to document seaweed specimens, and this work is an example of her influential contribution to both photography and botany. The image showcases the delicate structure and intricate patterns of the Halyseris polypodioides seaweed, captured in a stunning blue and white palette. The cyanotype process results in a striking, almost ghostly image that highlights the natural beauty of the subject.
