For the Triennial of Photography Hamburg, the Hamburger Kunsthalle, Hamburg, is presenting some 100 works by internationally renowned artists in an exhibition titled When There Is Hope. The photograph is today the prime medium for capturing dreams and fantasies, but also for expressing our search for identity and hope. As it reveals our yearnings and expectations, however, the photographic image also documents the cruel realities of social and political upheaval. The exhibition is devoted to these ambivalent and highly controversial aspects of the principle of hope in contemporary photography. Until 13 September.
