Most attempts to generalize about photography as a medium run up against our experience of the photographs themselves. We live with photos and cameras every day, and philosophies of the photographic image do little to shake our intimate sense of how we produce photographs and what they mean to us. In this book that is equal parts memoir and intellectual and cultural history, French writer Roger Grenier contemplates the ways that photography can change the course of a life, reflecting along the way on the history of photography and its practitioners.
