Henning Fehr and Philipp Rühr work primarily in the medium of film. Both studied photography with Christopher Williams at the Düsseldorfer Akademie. Their artworks are concerned with tensions in the relationship between fiction and reality. The position of the artists moves between active participation and passive observation. Die desinfizierende Sonne [The disinfecting sun] is a film on the function of central perspective in urban planning, architecture, and economy. The facades of a shopping street in Düsseldorf serve as the stage for a narration consisting almost exclusively of passers-by, cars, and tramcars. Seen through the display of a digital camera, the shops, black-and-white images filmed full-center from the opposite side of the street in their random succession, look like architectural drawings. Thus, the ideal perspective of the urban planners is projected into reality. These documentary-like images question the perception of passers-by, who, moving between the ideal images of the architects, are prompted to intellectually correct their own perspectivally distorted view.
