In this landmark photography publication and accompanying exhibition, Clément Chéroux demonstrates how Magnum Photos owes its pre-eminence to the ability of its photographers to encompass and navigate the points between photography as art object and photography as documentary evidence. A Magnum photograph can be expressive and bear witness at the same time. MAGNUM MANIFESTO is organized into three main parts: Part 1 (1947–1968) views the Magnum archive through a humanist lens, focusing on post-war ideals of commonality and utopianism. Part 2 (1969–1989) shows a world fragmenting, with a focus on subcultures, minorities, and outsiders. Part 3 (1990–present day) charts the ways in which Magnum photographers have captured—and continue to capture—a world in flux and under threat. The book features both individual photographs and in-depth projects that have shaped our view of the world, the book also includes contact sheets, notebooks, magazine spreads, and other previously unseen material.
