Heinrich Heidersberger (1906–2006) was a pivotal figure in postwar experimental photography, best known for his Rhythmograms, which introduced a systematic and time-based approach to image generation. Developed in the early 1950s, these works were produced through precisely controlled movements of light sources during long exposures, transforming photography into a mechanical and procedural system. Rather than representing external reality, Heidersberger’s images emerge from the interaction of light, motion, and duration, governed by predefined conditions. His practice exemplifies a generative logic executed through analog means, foregrounding process, seriality, and automation. Heidersberger’s work constitutes a crucial precursor to generative photography, anticipating later rule-based, algorithmic, and system-oriented approaches to image-making.
The exhibition " Gottfried Jäger and the Precursors of the Generative Photography", is on view through April 10, 2026. The exhibition brings together key works by early pioneers whose systematic and rule-based approaches laid the foundations of generative photography: Herbert W. Franke, Heinz Hajek – Halke, Heinrich Heidersberger, Roger Humbert, Peter Keetman, Hein Gravenhorst, Karl Martin Holzhäuser and Carl Strüwe among others.
