This volume brings together leading researchers concerned with ordinary citizens' contributions to photojournalism, particularly where capturing images of breaking news events is crucial to reportage. It offers an evaluation of how photojournalism is evolving in digital contexts, examining how today's emergent forms of co-operation, collaboration and connectivity between professional and amateur news photographers promise to improve photojournalism for tomorrow. This book was originally published as two special issues, in Digital Journalism and Journalism Practice.
