Is it possible to describe a photograph without interpreting it? Can a viewer ever be as dispassionate as the mechanism of a camera? And how far can a photographer’s intentions determine responses to their image, decades after it was made? These are just a few questions that David Campany eloquently addresses in On Photographs. In the tradition of Susan Sontag and John Berger, Campany explores the tensions inherent to the photographic medium – between art and document, chance and intention, permanence and malleability of meaning – as well as the significance of authorship, performance, time and reproduction.
