David Scharf is a scientist, a photographer, and an artist, specializing in Scanning Electron Microscope (S.E.M.) imagery. For over 30 years he has been an innovator in the science, technology, methodology, and photography of this uniquely fascinating form of imagery. His images define the state-of-the-art in this area of science and technology. In the early '70s he developed techniques to keep many plant and animal specimens alive and in their "natural state", bypassing the traditional methods of killing, fixing, dehydrating, and gold coating, and thereby showing images of life-forms with clarity and realism never before seen.
