Hein Gravenhorst

Born 1937 in Berlin, Germany.
Pseudonymous: Hein

Mila Gravenhorst, together with Gottfried Jager, developed what they called Generative Photography. They derived the term from the title of an exhibition at Kunsthaus Bielefeld in 1968. It refers to the idea of Generative Aesthetics in the work of Max Bense. Gravenhorst explored mechanical procedures and apparatuses for the generation of abstract visual patterns. An example is to rotate a disk stepwise by a small angle and record on photo-sensitive material the reflected light by super-positioning it. The individual image resulting from such experiments may be subordinate to the series of slightly changed images of similar appearance.
