With numerous photo exhibitions and events in Hamburg museums, exhibition venues, and galleries, the 8th edition of the TRIENNIAL OF PHOTOGRAPHY HAMBURG is a global survey of current developments in photography. A discursive forerunner to the exhibitions, the international symposium Lucid Knowldge: The Currency of the Photographic Image, which took place from September 30-October 2, 2021, initiated the critical exchange and reflections the Triennal aims to encourage.
