The newest book from Bryan Peterson, released in March 2009, it cannot help but come in direct comparison with John Shaw's primer on macro photography.
However, this is a book on CLOSE-UP photography and that should be kept in mind when reading it. While macro is covered as much as close-up photography, both are given strong emphasis and many techniques can be applied to either situation.
This book goes into good detail about nearly every aspect of close-up and macro photography you might want to know a bit about: equipment, lenses, filters, diffusers, reversing rings, good point and shoot cameras, tripods, reflectors, ring flash, etc. However this will be a 'bit' about each one. On some, such as lighting topics, there are entire books out there written just on those subjects.
Depth of Field is covered very nicely and in more detail than Shaw's book, tying it in with composition, lighting and artistic decisions.
Overall, this is an excellent book and very up to date, printed March 31 2009. The cameras, lenses and other items mentioned are ones we are all using today or might buy. Artistically, the ideas are presented in a way that make you want to pick up your camera and go see what you can find. Readability wise, Peterson is an excellent writer and teacher which make this book very accessible to photographers at any level.
