Callithamnion hookeri c. 1843 - 1853

Anna Atkins, a pioneering photographer, created "Callithamnion hookeri" as part of her groundbreaking work, "Photographs of British Algae: Cyanotype Impressions," which was published between 1843 and 1853. This cyanotype, a photographic process that utilizes light-sensitive iron salts, depicts three delicate specimens of Callithamnion hookeri, a species of red algae. Atkins meticulously arranged the seaweed specimens directly onto the paper and exposed it to sunlight, capturing the intricate details of their structure. This image showcases her artistry and scientific expertise, highlighting the beauty of nature through the medium of photography. Atkins's contributions to photography and botanical illustration were significant, establishing a legacy in the field of scientific and artistic exploration.
