Photography is the center stage of the artistic production of Christopher Williams who followed Bernd and Hilla Becher as professors at Kunstakademie Düsseldorf in 2008. Williams does not take photographs on his own but understands the technical aspect of conceptual media and visual deployment which can help analyze the history and conditions of industrial societies. His ongoing series of exhibitions entitled “For Example Dix-Huit Leçons Sur La Société Industrielle“ Williams is based on pictures of commodities, modern architecture, optical instruments, and portraits. By the objective aesthetic of this body of work, Williams creates a typology of photographic manifestations. Furthermore, his presentations refer to the tradition of institutional critique as the reflection on the exhibition space as well as the rhetoric of the hanging is part of his conception all the time. For Texte zur Kunst Christopher Williams has conceived an inkjet-printed laconically entitled “C, 2010”. The sheets depict the graphic figure of a gate-blocking light which the artist found in a Dutch manual from the early seventies explaining how to build a domestic darkroom in four steps. Like his other works this print also shows Williams' interest in the photographic medium and its social, ideological, and economic implications. Taking a look at the borders of photography the artist examines how the contemporary standards of the order of the visible were set by this technology.
