This book is an excellent anthology of contemporary, i.e. "art" photography and photographers. I am not in the lucky position to be a "collector", but nevertheless the book makes an interesting read and introduction to this type of art. It covers the work of 40 photographers.
It provides several examples of each photographer's work, along with information about how the images were made and the philosophy behind them. The boks final chapters include one with a potted biography of each photographer. The book is portable yet well printed and is well worth buying.
