This unique book takes a thematic approach to twentieth century photography by focusing on the major developments of the 20-year periods into which the book is divided rather than on individual photographers. Photography 1900 to the Present presents excerpts from a cross-section of writers in the fields of photographic criticism and history on topics relevant to each period with the overview of each section providing a context for the art and culture of that era. The book also includes a timeline to exhibits, books, technical innovations, and professional organizations of each period. It also includes a bibliography of major periodicals dealing with 20th century photography. This enables readers to access current information on contemporary photographers. A valuable reference book for any reader interested in the evolution of 20th century art and photography and its impact on society.
