This book teaches the reader how to proactively take control of studio lighting to achieve exactly the effect they want.
Topics such as shadows, highlights, shadow/diffused edge transfer, highlight/diffused edge transfer and reflections are covered in detail with both theory and examples of how to manipulate the lighting to achieve any desired combination. The author demonstrates the evolution from first effort to finished shot using multiple diagrams, pictures and text so the reader can easily follow his thought process.
For many of the examples, minimal equipment is used (in fact, many only use a single light with reflectors and diffuser) so you don't need a big budget to start putting the ideas into practice.
Studio examples include still life and portraiture but there is also an informative example of a portrait shot outdoors mixing daylight with flash.
Overall, this is a great read and one which I will refer back to again and again.
