It would, I suppose, be possible to see Bernd and Hilla Becher’s pictures of industrial structures as boring, particularly if one were to restrict one’s attention to one or two pictures, though for me I think fascination with the detail always wins out. These are perfect pictures. They record the appearance of industrial structures – water towers, gas holders, mine heads etc – with complete objectivity and in forensic detail. The pictures were made over a period nearly five decades – they started collaborating in 1959 and continued until Bernd Becher’s death in 2007 – using a large format camera in the neutral lighting of overcast weather. The structures are viewed straight on, so that verticals remain vertical; the large format camera helps here but the Bechers also worked from raised viewpoints so that we are looking at the structures as directly as possible.
