Here's a case where Amazon's star rating sytem doesn't work very well. As described below, for a very small number of photographers this book will prove useful. For the vast majority of photographers it will not.
I've long been an admirer of the work of Bruce Barnbaum. An original Barnbaum print hangs on my wall. A copy of his book of photographs, "Visual Symphony" graces my coffee table. Several years ago I purchased a used copy of the original, but then out of print, "The Art of Photography" at an outrageous price. I have to confess that much of the book was unread because it dealt with film photography, and I had long since made the switch to digital.
Now "The Art of Photography" has been reissued in a revised form, supposedly updated for the digital age. The book attempts to cover all of photography from visualization to hanging the print on the wall. There are even chapters that discuss ideas like innovation and old saws like truth in photography. There are references to digital photography, but a great deal of the book is devoted to Barnbaum's take on the zone system for film photography, including processing film to increase (or decrease) the range of light captured on the negative. There is a tip of the hat to digital photography, including the importance of the camera's histogram to capture exposure, and reference to high dynamic range photography to increase the range of light for digital captures but the heart of the book is film. The book is illustrated with Barnbaum's photographs, mostly in black-and-white, and they are drop-dead beautiful. If you like Ansel Adams you will love Bruce Barnbaum's images.
I suppose these images alone may justify the updating. Certainly the content will be interesting to those who still practice black-and-white film photography, although I suspect that these folks, already being specialists, may be familiar with what the author has to say. (I really can't comment on that; it's been years since I worked in a chemical darkroom.) The digital photographer will find that there just isn't enough detail in looking to this book for technique. It's a shame because I would have loved to see an explanation of how to achieve Barnbaum's beautiful effects in Lightroom or Photoshop.
The sections on the artistic aspects of photography are interesting but somewhat elementary. Barnbaum doesn't succeed in telling us what it is in an image that turns it from just an image to art. (Of course, I really don't know any authors who do this, although there are several people, most recently George Barr in "Why Photographs Work: 52 Great Images Who Made Them, What Makes Them Special and Why", who have made valiant efforts to accomplish this impossible task.)
The bottom line is that if you are unfamiliar with Barnbaum's work, this book is worth it for the images. If you are a film photographer, the technical data may prove useful. If you are a digital photographer looking for technical help, look elsewhere.
