The fact that a book has reached its fourth edition usually means it has some merit that readers have found useful. If that's the case with this book, it's a mystery to me how the book ever got out of the first edition.
First of all, the title "Single-Camera Video Production" led me to believe that the book's focus is on how to do everything for a video production using a single camera. For the bulk of the book, that's not what it's about. It's really a general book about using a video camera. (One section even illustrates using 5 cameras--rehearsing and preparing talent!)
Second, the illustrations are terrible. They look like they were done by a non-designer using Etch-a-sketch. Further, the drawings of the complex video cameras were so generic and seemingly dated that they were totally useless. However, that didn't matter because I didn't buy the book to learn about video cameras (that keep changing regularly), but rather some wisdom on the production process where the videographer is trying to produce using a single camera.
The reason that this book is rated two-stars instead of 1 (or 0) is because there were some materials on lighting with a single camera that were useful. (However, there was nothing unique and that I couldn't find on the Web for free.)
All in all, this book is a poorly crafted one, and one that I could cobble together with a topic search on the Web. Unfortunately, I think that a good book on Single-Camera Video Production is something that would be very useful. This just isn't it.
