Callithamnion floccosum c. 1843 - 1853

Anna Atkins, a pioneer of photography, created this cyanotype print, *Callithamnion floccosum*, sometime between 1843 and 1853. Atkins's cyanotype process captured delicate details of the *Callithamnion floccosum* algae, rendering its fine branches in stark white against a deep blue background. This image, part of a larger collection of cyanotypes documenting British algae, is considered one of the earliest examples of photographic photo-documentation.
