Thinking between diagram and image: the ergonomics of abstraction and imitation

The work of the American painter Jackson Pollock speaks to us not only through exhibitions of paintings hung on gallery walls, but also through the films and photographs[1]of Hans Namuth which exposed Pollock's phased working process to the public. In the first of two distinct phases Pollock is seen immersed in, and in intimate interaction with, a large horizontal canvas. This records traces of his movement and expressive gestures in heterogeneous media. A second phase is then triggered by a pivotal operation: the horizontal recording and working surface is transposed to a vertical viewing plane. Leo Steinberg recounts that Pollock: ‘would tack the canvas on to a wall – to get acquainted with it, he used to say; to see where it wanted to go. He lived with the painting in its uprighted state, as with a world confronting his human posture’.
