Few people ask, "What is a painting? A drawing? A sculpture?" But the medium of photography, especially since the 1970s, has been constantly changing as technological developments allow for endless experimentation - until the very definition of a photograph becomes ripe for debate. Beginning with the waning days of conceptual art, this book presents a wide variety of artists - among them James Welling, Christopher Williams, Uta Barth, Marco Breuer, Alison Rossiter, Parker Ito, Sigmar Polke, and Gerhard Richter - who have reconsidered and reinvented the role of light, color, composition, materiality, and subject in the art of photography. Brought together for the first time in book form, these individuals have found new ways of implementing both analog and digital technology, in many cases creating hybrid works that open up new possibilities for today's artists. Filled with brilliant colour reproductions, this volume not only traces the many strands of experimentation that have developed out of conceptual art, but also encourages dialogue on the continuing experimentation that is occurring as photography continues to evolve within the analogue and digital worlds.
