As you probably already know, Trey Ratcliff - the guy behind StuckInCustoms.com, the #1 travel photography blog in the world - released in December a great book called A World in HDR, which I had the pleasure of reading. The book presents the art of HDR mastered by Trey Ratcliff, and it presents it with a very nice sense of humor and passion that it makes you really excited to try it out if you are a beginner, or to improve your skills if you are already a pro.
