This artist's book centers on Andrzej Steinbach's eighteen-part photographic series Erweiterungen (Extensions) from 2024. In rooms characterized by no-nonsense staging, we encounter a figure who shows us items of technology, tools, and everyday objects. The images engender relationships between bodies and things, displacing familiar ascriptions. Erweiterungen continues a sequence of works in which Steinbach uses a photographic setting, combining elements of enactment and the case study, to investigate social roles and the gestures and codes associated with them. A substantial section of the book is devoted to images presenting Steinbach's artistic practice outside of photography, covering his sound and video works and his sculptures. The appendix joins the dots between interconnecting facets of his oeuvre, bringing together its different aspects, and expanding our view of Steinbach's formal language and method of working. Andrzej Steinbach (b. 1983 in Czarnków, Poland) lives and works in Berlin and Brussels.
