This is a great book for photographers of any ability as it has useful nuggets of information in there for all. Photography is a continual learning process and I only wish I had had access to this book sooner. It reviews photographs and explains what makes them great. It doesn't matter whether you like the photo or not to understand what makes it work as a composition, or as a technically good photograph. By taking this informaiton, you can choose what to add to the mix of your own creative process. Or not. Easy to read and understand, I have found it useful.
