For this series he photographing landmarks as multiple exposures.
It launched in Berlin, his hometown for 40 years, but then he extended this kind of photography to other citys. For this series he use exclusive analogue film material in both dimensions (35mm and 6×6) and only b&w.
He photograph buildings, landmarks and citytrees from several positions on one frame. The objects are taken from different perspectives, as well as the different visitors they look. The multiplication and intensification of positions and fields of view appears to distort the structures and reduce them to their core. They literally vibrate under the attempt to capture the time even in the pictures.
His equipment are a 35mm film camera (Nikon) with a strong wide-angel lens and a good old Hasselblad 500 with a 50mm lens. [Official Website]
