In Anna Atkins' creation, we can see how she captured the outlines of Dictyota dichotoma, a type of algae, on a cyanotype. By placing several pieces of algae on a chemically treated paper and exposing it to sunlight for several minutes, Atkins was able to engrain the outlines of the plants onto the now blue paper. Washing the paper after exposure to sunlight removed any excess chemicals in order to stop the exposure process, and after several days the image would have gone from a greenish-blue to the deep blue that many people associate with a cyanotype.
Since Atkins was a botanist, her goal was to capture images of the plants in an accurate way. She did this successfully, in both an aesthetic and technical sense. She positioned the plants in a way where all of their parts can be seen, and exposed the photo correctly so that a certain level of transparency allows the leaves to be slightly translucent, as they are in real life. Overall, the image is successful.
