Karl Blossfeldt was a German photographer who lived from 1865 to 1932. He didn’t think himself a photographer. With his studies of plant forms he made an enormous contribution to plant photography. Here is a nice wikipedia article about him.

He started to do photograms. Plants or parts of plants were placed directly on film or paper suitable for exposure. Exposure then takes place without any optics. Later he built himself a wooden camera, which reminds me of Andreas Feininger.

Black and white backlit macro images with a background can be similar to Blossfeldt’s images.
