The biennials, festivals, and educationalspaces changing the shape of Africanphotography.

Aperture takes a detailed look at the dynamic spaces that have shaped conversations about photography in Africa for the last twenty-five years-the biennials, experimental art spaces, and educational workshops in which artists and audiences interact with photography. Platform Africa presents a new generation of artists, and is produced in collaboration with guest editors Bisi Silva, founder and artistic director of the Centre for Contemporary Art in Lagos, Nigeria; John Fleetwood, director of the South Africabased platform Photo and former head of the Market Photo Workshop in Johannesburg; and Acha Diallo, associate editor of Contemporary And.
