Rivularia nitida c. 1843 - 1853

"Rivularia nitida" is a cyanotype photograph created by Anna Atkins between 1843 and 1853. Atkins was a pioneer in the use of cyanotype, a photographic process that produces a blue print. The image depicts various specimens of the Rivularia nitida algae, arranged against a blue background. Atkins was one of the first photographers to use the cyanotype process to document the natural world. She created a collection of photographs of plants and algae, many of which were included in her book "Photographs of British Algae: Cyanotype Impressions".
