By the time the first photographs were taken at war in the late 1840s, the idea that ''the camera cannot lie'' was already firmly embedded in the Victorian psyche. ''Truthful'' in a way the work of the war artist could never be, despite the initially long exposures and cumbersome equipment, cameras have been used to document war ever since the celebrated photographs of Roger Fenton in the Crimea. Through a rich selection of images – many of them never before published – this book tells the story of the photographers who chronicled Britain''s Victorian and Edwardian wars and those who fought in them.
