I have reviewed this book reflecting it's claim to be a landscape master class, and as such it falls way off it's mark. The main fault of the book is that the comments and explanations are without reference to any theory or principals that the reader can become acquainted with and apply in his own images. However, if you are satisfied with a collection of beautiful images it more or less serves fits the bill.
The book is divided into three parts with one for each master photographer. Each section starts with a presentation and some background on how he came to be a landscape photographer. Nice as an introduction, but I really expected more than this. Accompanying the introductions is a small selection of some 4 photographs with some notes on practicalities for managing to capture the image. However, with few exceptions they are not referenced in the text - so why are exactly these photographs included? They are really nice, but what I am expected to learn from looking at these images instead of some other images is unclear to me. Both JC and CW write about images that have inspired them, but you will not find them in the book (I know, Google..). A potentially interesting feature is the inclusion of some images that they claim don't make it. However the images are relatively small and accompanied by a brief explanation containing what appears to be some thoughts passing at the time of writing.
After each photographer's introduction follows a portfolio of images from contributing (amateur?) photographers. The portfolio contains several quite stunning images and ends with a brief commentary on each image by the master photographers. Unfortunately there is little in the comments that will advance you in your own photography. One of the better comments (p 55):
"JC: If Ansel Adams had been a color photographer he would have shot this. It has a soaring, almost Wagnerian quality. There's not much to add. CW: The very bottom is left out of focus, but who cares. One could argue that it's a bit tight on the top; some more sky might have helped - perhaps not. I like that you don't se the source of the light. It is a marvelous picture. DW: Yes, I particularly like the compressed perspective as well."
Really, in my opinion several photo sites do better than this. Other comments contain information such as to use your hand to eliminate flare, or that the photographer handled the subject well since he did not burn out the highlights of some running water. Hardly master class material.
Finally, preceding the commentaries is a page where the master photographers comment on each others images. Actually, on first reading I failed to appreciate that this wasn't written by the photographer himself. So much for critics.
Nice images that may serve as inspiration, but don't expect much to further your photography. I suggest you take a look at : Landscape Beyond: A Journey into Photography.
