I'm not sure what caused the sudden surge in sales, but the book that I wrote that is based on this blog Jeff Wignall's Digital Photography Crash Course: 2 Minute Tips for Better Photos (Lark Photography Book) made it to the top 3,000 books (among all books) on Amazon today. And it landed in the "Top 10" of all photo books. In other words, it's a bestseller. As I said, the book grew out of this blog and it features roughly 150 or so tips that each began as a posting on this blog. The tips were expanded in most cases and I added extra illustrations, but the real genesis of the idea was this blog. What's really amazing to me is that the book is selling even better than my flagship book, The NEW Joy of Digital Photography (Lark Photography Book). Go figure! The Crash Course book was reviewed this week on a few blogs--including a major photo blog in Australia--so perhaps that is helping. In any case, I love having another bestseller! I'm sure you can find it at the local Barnes & Noble if you are looking for a last minute gift (and who isn't?).
