Double or multiple exposures are an illusion created by layering images (or portions of images) over the top of each other. This can be achieved in the camera settings, or on Adobe Photoshop by creating LAYERS and then using BLENDING OPTIONS and OPACITY CONTROL. Artist have used these techniques to explore Surrealist Ideas and evoke dream-like imagery, or imagery that explores time / time lapse.

Since 1959 Bernd and Hilla Becher have been photographing industrial structures that exemplify modernist engineering, such as gas reservoirs and water towers. Their photographs are often presented in groups of similar design; their repeated images make these everyday buildings seem strangely imposing and alien. Idris Khan’s Every… Bernd And Hilla Becher… series appropriates the Bechers’ imagery and compiles their collections into single super-images. In this piece, multiple images of American-style gabled houses are digitally layered and super-imposed giving the effect of an impressionistic drawing or blurred film still.
