The folders series, consisting of photographs and paper works, all in the A4 format, has accompanied Albert Weis’ investigations of urban structure for ten years now, rather like a three-dimensional diary. The photographs open up a view into spatial depth or spatial height. They are detailed views of façades and bands of windows, into corridors or through panes covered with blinds that make the interior or exterior view less well defined. The disturbing volumes and surfaces in the photographic views are related to the three-dimensionally folded and coated papers. Here we see a conceptual approach to large-scale sculptural thinking.
