The Collectors Series edition of "In Focus" is simply the existing book at a smaller trim size. This magnificent collection of 280 photographs by many of the world's greatest photographers tells the tale of portrait photography over time in page after page of arresting images. Each photograph stands proudly on its own, yet taken together, they tell a much more complex and subtle story of the ever-evolving art form in constant creative response to new ideas, new eras, and new technologies.
