Since the Sixties, artists producing work of a transient nature (perhaps made for a specific site, for a limited duration or from perishable materials) have made use of various recording instruments in order to document their practice and give it a form of continued existence. To this end, the camera has been widely and successfully deployed, but has also caused questions to be raised about photography as a reliable source of evidence – not just in connection with works of art, but in a broader context. In addressing this issue, Prof. Hilliard has sought to conduct a critical interrogation of photography as a representational medium, but also to disclose and celebrate its specificity. Many of its perceived failings (blurred or unfocused images, for example) might equally be considered as unique assets. Indeed, through a catalogue of errors one may yet arrive at one’s correct destination.
