I've been an --off and on-- working photographer for twenty years, doing PR and, latterly, advertising. I bought this book to help kick-start new ideas, but found that it really wasn't that interesting at all. It isn't a book of amazing images -- you can browse Flickr for much more compelling stuff -- and it's advice on shooting is not going to come as news to anyone with a bit of experience.
What I really got from this book was that browsing for ideas just isn't a good way of developing ideas. Much better to begin with concepts like brand, outcome and message and work from there, or else to explore a particular set of techniques -- portraiture, modelling, macro etc -- in depth and be inspired to produce something new.
Regrettably, it's now sitting on my shelf prompting the thought 'why did I ever buy that?' every time I see it.
