“Camera Recording its Own Condition (7 Apertures, 10 Speeds, 2 Mirrors)” (1971) by John Hilliard
This series consists of photos of Hilliard’s own camera, taken using mirrors and different combinations of aperture and shutter speed. Hilliard’s fingers can be seen operating the camera. Photography is both the medium and the subject of the work, giving not a picture of ‘reality’, but different versions of reality.
