Francis Bacon famously found inspiration in photographs, film stills, and images from the media. In this new, updated edition of In Camera, Martin Harrison reveals how these sources informed some of Bacon's most important paintings and triggered decisive turning points in the artist's stylistic development. Key influences--including the masters Diego Velázquez, Nicolas Poussin, and Auguste Rodin; the photographer Eadweard Muybridge; and the film director Sergei Eisenstein--are given close consideration. Bacon's work is examined in relation to the precedents set by other artists who made use of mechanical reproductions, including Pablo Picasso and Walter Sickert, and in the context of his contemporaries Lucian Freud, Mark Rothko, Graham Sutherland, and Patrick Heron. With over 270 color illustrations, including valuable source images and documents, In Camera is a bravura accomplishment of original research, addressing important questions about Bacon's painting practice and shedding fresh light on his life and work.
