(b Basle, 12 April 1946). Swiss photographer. He studied photography at the Gewerbeschule, Basle (1964–7). After being apprenticed to American photographer Will McBride in Munich, he opened his own studio in Basle in 1970. From 1972 he worked for various magazines, such as Du, Camera, Time-Life and Playboy. His photographs were created in clearly defined phases, such as his ‘blue period’ with tinted prints (1973–5) or the ‘frame’ series (1975) of photographs in which a rectangular frame photographed inside the field of view became the parameter for a picture within a picture (e.g. Without Title, 1975; Basle, Antikenmus.). His best-known series of erotic self-presentations of women, with a wooden crate as a prop (1979–81), explored a similar principle. His photographs often implied reflections on the photograph itself, on its subject, its selection and the relationship between what was shown and what was left out.
