I am in the middle of reading Karl Blossfeldt's, The Complete Published Work. A German photographer (1865-1932) who used a home-made large format wooden camera to catalogue plants primarily to serve as a teaching aid for drawing classes. He was a professor of art at The Berlin College of Art. His photographic work was discovered later in his life. His work has certainly inspired me to shoot tiny plant details and remove color to leave behind a simple composition of a plant's form.
