The book was written to introduce students to photography. It does not require that students possess any technical know-how and can be taught without referring to techniques in photography. Incorporating the latest research and international uses of photography, the text surveys the history of photography in such a way that students can gauge the medium's long-term multifold developments and see the historical and intellectual contexts in which photographers lived and worked. It also provides a unique focus on contemporary photo-based work and electronic media.
