For Anna Vol. III is an homage to the 19th Century English botanist and photographer Anna Atkins, the first person to publish a book using photography to scientifically illustrate the world around us. While viewing Atkins’ book Photographs of British Algae in person last year, Riepenhoff was struck by a series of consistent burnishing marks, most likely caused by jewelry worn by someone turning its pages. Debris and residue from human contact affected not only single pages, but those pages preceding and following, fading according to proximity. Riepenhoff’s response takes the form of a book of cyanotypes made in the ocean, exposed by the sun, and washed by the waves. Where Atkins made traditional photograms with dried botanical specimen, Riepenhoff gathers wet seaweed onto the paper and leaves it in place, forming literal impressions of its shape and texture, as well as its found environment.
