To be able to follow dozens upon dozens of the most recognised images of the 20th century backwards through the selection process gives these pictures a new immediacy and vitality ... fascinating and surprisingly intimate' - John Banville, Daily Telegraph 'Magnificent ... every compelling image gives us an intimate and exciting sense of walking alongside the photographer' - RA Magazine 'A treasure trove' - Andrew Motion, Guardian 'A fascinating book that can not only be enjoyed for itself but can be utilised as a great learning tool for the most difficult task of all – picture editing' - Black & White Photography
