Karl Blossfeldt (1865-1932), a German artist and professor, captured these 'art forms in nature' and used them to instruct his students. These close-up photographs of plants really take my breath away, the beauty in the natural world is just amazing to me. The images are so powerful in black and white and I would love to start a collection of his prints.
Really, I can't get over these.
