The objectivity that characterises Bernd and Hilla Becher’s recording of industrial architecture resulted in pictures that allow examination of the structures in almost forensic detail and their typological approach to display allows comparisons between buildings of the same type. The precision that comes from using a large format camera and the neutral lighting of an overcast sky makes for an extraordinary level of detail. There is a sense of completeness that comes from seeing multiple structures of each type.
Idris Khan has taken the Bechers’ work as a starting point for a different examination of the same territory. Rather than building up a picture of the whole from the precise detail of each individual image, Khan has taken an average. By overlaying all the Bechers’ images of a particular type of structure – for instance spherical type gasholders – Khan has produced sketchy pictures that seem to suggest an approximate version of how each type of building might be expected to look.
