Considered to be 'basic' by some, Shaw does an extraordinary job of covering the basics as well as all ranges of macro photography -- with and without macro lenses. His specialty is in the field and he discuss several set ups to help you out there (umbrellas, flash brackets, etc).
The photos alone are inspirational -- you look twice and realize that you've seen such scenes but never thought to compose them into a macro portrait.
His descriptions are clear and concise although he is 'old' school and digital is not discussed at all. In all, there is not much to be skipped in talk of slide film speeds and much still to be gained in learning how to calibrate your set up for middletones and other situations. Anyone who has been taking macros because they have a macro lens, or who wants to understand it more, can definitely benefit by reading through this book.
