"Masters of Photography" contains a good introduction to the life and work of many important photographers. For each photographer, the book includes a few key facts, half a page with biographical and background info, and 3-5 typical images. With several dozens of photographers covered, the book focuses on presenting a broad number of photographers, rather than on an in-depth approach of the work of the greatest of them. This makes the book particularly suitable as a beginner's guide. I have some minor doubts on the selection of photographers (I would expect to find e.g. Josef Sudek in the book) and images presented (the images of Cartier-Bresson are not his most typical, I feel), but overall the book is fine as an introductory book and a guide for further reading. The presentation of the photographers is done in alphabetical order; personally, I would prefer some more elaborated classification (e.g. by genre). The accompanying texts are well-written and concise.
The price is attractive and the print and binding quality are good. My biggest complaint is the format of the book, which is unnecessarily small. This results in many photographs being split in two pages, which severely damages their aesthetics.
Overall, the book is a good beginner's guide to the masters of photography, with a very good value for money.
