With her medium-format camera, Ann-Kathrin Müller takes us on a journey to a seemingly out-of-time seismological measuring station somewhere in eastern Germany. The black-and-white photographs, which show the interior of the station and the deserted surroundings, conjure up a diffusely haunting atmosphere.

Accompanied by Judith Engel’s short prose pieces, a patchy dialogue between images and texts emerges, blurring the lines between past and present, fact and fiction — completing this artist book. In the setting of this opaque world, “Das Signal” questions the unambiguity of purely rational and scientific worldviews, repeatedly encountering a phenomenon that accompanies both science and photography in their search for evidence: Blur.
