Degrees of Stillness is a remarkable book, made possible by a remarkable collection that includes photographs by Etienne-Jules Marey, Alfred Stieglitz, Man Ray, Robert Mapplethorpe, El Lissitzky, Berenice Abbott, Richard Avedon, Sally Mann, David Hockney, Robert Rauschenberg, Roy Lichentstein and Andy Warhol. In an interview in 1995 Manfred Heiting said, "The only thing that unifies my collection is my passion for what is to me beautiful about photography. It was and is my goal to represent in my collection the history of the medium and its numerous applications, from about 1840 to the present." Almost every genre and every technique is represented. Detailed captions provide in-depth descriptions of each work"s origin and the motivation of its creator, and a comprehensive index carries technical details. English/German
