Blast furnaces, winding towers, processing plants – now largely destroyed evidence of industrial development – live on in the photographs of Bernd and Hilla Becher. In the documentary film 'The Photographers Bernd and Hilla Becher', the now deceased artist couple talk about their life, work and influence, which was devoted to photographing industrial buildings for four decades. The portrait of the renowned photographers is complemented by contemporary witnesses such as their son Max Becher and former students of the Düsseldorf Art Academy, including Thomas Struth, Candida Höfer, Thomas Ruff and others.
