The posthumous investigation of Bacon’s studio confirmed the extent to which he used and manipulated photographic imagery. This practice was already known from montages recorded in the early 1950s by the critic Sam Hunter. Often united by a theme of violence, the material ranges between images of conflict, big game, athletes, film stills and works of art.
An important revelation that followed the artist’s death was the discovery of lists of potential subjects and preparatory drawings, which Bacon had denied making. Throughout his life, he asserted the spontaneous nature of his work, but these materials reveal that chance was underpinned by planning.
Photography offered Bacon a dictionary of poses. Though he most frequently referred to Eadweard Muybridge’s survey of human and animal locomotion, images of which he combined with the figures of Michelangelo, he remained alert to photographs of the body in a variety of positions.
A further extension of Bacon’s preparatory practices can be seen in his commissioning of photographs of his circle of friends from the photographer John Deakin. The results – together with self-portraits, photo booth strips, and his own photographs – became important prompts in his shift from generic representations of the human body to portrayals of specific individuals.
