How does photography serve to legitimate and normalise existing power relationships? How does it serve as the voice of authority, while simultaneously claiming to constitute a token of exchange between equal partners? What havens and temporary escapes from the realm of necessity are provided by photographic means? What resistances are encouraged and strengthened? How is historical and social memory preserved, transformed, restricted and obliterated by photographs? What futures are promised; what futures are forgotten? In the broadest sent, these questions concern the ways in which photography constructs an imaginary economy.
