“Dimensioning photography” is how the artist Hubertus Hamm (b. Werdohl, Germany, 1950; lives and works in Munich) describes his approach, for which he has adapted a strategy from theoretical physics and mathematics to photography. Inspired by the operation of adding new dimensions to allow complex problems to be understood, he seeks to redraw the limits of photography’s representational capacity beyond the moment of exposure and the flatness of two dimensions. The publication consolidates a number of individual works and ensembles in which Hamm brings this position, which evolved in over forty years of creative and experimental photographic practice, into sharp relief. It presents the artist and photographer’s most recent work – pieces whose conceptual orientation and technical realization make them playful and yet insistent inquiries into the materiality and dimensionality of photographic visualization. Taking stock of his art, the book is also an invitation to discursive engagement. With essays by Andreas Beitin, Helmut Friedel, Alexandra Grimmer, Benjamin Tillig, Tilman Treusch, and Björn Vedder.
