There are legitimately good books on the subject of making money with digital photography like 2008 Photographer's Marketand Best Business Practices for Photographersbut they are a tad bit bland and not very inspiring. Dan Heller's book takes a different approach and is filled with great pictures and plenty of inspiration. It is clear from reading this book that Dan is a great guy and an excellent photographer, but sadly that is really all that this book offers.
This book is a short read (maybe a couple hours at most) and when you are done you get the feeling that the way Dan makes his money in digital photography is by ripping you off with nonsense like this book. Sure, it is a great picture book for Dan, and he means well, but he spends a lot of time going over basics that are covered by every photography book on the planet (i.e., what types of memory cards you need) and he is very noncommittal in his advice making this book utterly useless. Well, that might be a bit harsh as there may be a nugget or two for some people (especially in his section that shows the math behind selling postcards) but overall I felt like this book was a waste of time based on the title. If it was called Dan Heller's Picture Book with Anecdotes and Lessons Learned, then I'd say it was an excellent book. However, that wasn't the title so I say pass on this book unless you just want inspiration from his great pictures.
