Description:I did not buy this book but borrowed one from local library. But I have to say there's quite a lot errors even though I have just read several pages. For example, when it comes to exposure, 1000th of a second at f/4.5 at ISO200 apparently does NOT equals f/16 at 1/200 of a second with an ISO of 200, as the author claims. There are several similar errors in the same chapter.
So I would not recommend this book. I'm not sure whether the author is good at shooting, but he is not good at playing with numbers for sure, or at least not good at proof reading.
