Here’s another good reference book, Lighting and the Dramatic Portrait by Michael Grecco. It is an inspirational book that blends the best of the Rotovision series of books (lighting diagrams / camera info) along with interesting behind the scene anecdotes of a celebrity photographer (“We were shooting at Shaq’s home…”) The first sections are based more on types of gear and how to use them: cameras, lighting etc. Later chapters are based on concepts and case studies. Well written, great images, a quality book.
On Michael Grecco’s website you can also get a good idea about his lighting setups by looking at his behind the scenes video clips. I particularly liked this clip showing a portrait of Scorsese, it shows a clever use of natural and strobe light along with a bit of smoke.

A really good youtube video. It’s always interesting to see what it takes to set up that perfect photograph.
