Monochrome City consists of fourteen large-format direct exposures that I made from the top floor of the Haus des Lehrers (Teacher’s House) on Berlin’s Alexanderplatz. The photographs were made over the course of 2001, when my studio was located there. They depict either the view down onto Alexanderplatz or the view in the opposite direction, looking back into the building. ‹Monochrome City› employs the principle of the camera obscura—that is, all of the images are exposed directly onto the paper, and thus they appear as negatives and mirror reversed. The exposure time of each photograph ranges from a few hours to several days. To take the photographs I first built a box based on the proportions of the building and the dimensions of the window openings, then I converted the whole studio space into a camera. The work consists of several perspectives: four horizontal views outward (north, south, west, east), four vertical views down the facade of the building toward the street (north, south, west, east), and four views into the house (wall, ceiling). The view into my studio is also the view into the camera, since for two architectural details the whole studio functioned as a pinhole camera. They show Kaufhof and the Forum Hotel, two buildings that stand on Alexanderplatz, boxlike and solitary, much as the Haus des Lehrers does. The sightlines touch the building, but they leave it like a vacant space in the center of the work.
