Since the early 1980s, the photographs of Clegg & Guttmann have explored the representation of power and the codification of gestures. Famous for their images of powerful people or families inspired both by seventeenth-century Dutch painting and commissioned portraits for annual reports, they have developed various typologies of photographic portraiture over the past three decades. This volume examines two typological series in particular: Portraits and Artworks and Collaborative Portraits. These series feature artist sitters such as Sari Carel, Joseph Kosuth, David Robbins, Christoph Schlingensief, Joseph Strau, Franz Erhard Walther and Franz West.
