This probably deserved a higher rating when it was published, but now it is showing its age and is less relevant with the blizzard of images we receive from war zones.
On a technical level, the copy that I had doesn't seem to have really good reproductions of the photos but this could be due to the age of the book.
It is an interesting history and deals with the moral question of a photographer in a war - should the photographer be there just to document, or to take a position? Should the photographer intervene?
