If you're a complete novice in PINHOLE photography looking for instructions to start a little project (making a simple pinhole camera), then this book is not for you. However if you've started pinhole photography for a while and want to enter the next level and seek some more inspirations, this book is a pretty good one. It starts from the history of the camera obscura, and the origins of the perspectives devices...

Why I rated 3 is because I think the overall text is a bit boring and theoretical......

The last section which contains examples from other pinhole photographers are worth looking though. You'll be inspired to read some other books and construct your camera. As I said, this book is too technical for a novice.
