Marco Breuer (born 1966) is a German photographer. Much of his work is undertaken without the aid of a camera, aperture, or film, being instead produced through a combination of photogrammic, abrasive, and incisive techniques. Breuer works in and outside of the darkroom, exposing photographic material to heat, light, and physical abrasion. Drawing implements have included 12-gauge shotguns, the guts of electric frying pans, modified turntables, razor blades, and power sanders.
