Thanks for the kind comments about the book.
One thing it does not really stress sufficiently is that it is much easier to shoot Hollywood-style portraits with an 8x10 inch camera and uncoated lenses. Even 4x5 inch doesn't have the same look.
The original Hollywood photographers sometimes used HUGE lamps from the movie studios themselves -- often 2K, sometimes 4K and 10K -- but the likelihood that you'll be using less powerful lamps is offset by the availability of faster films.
Another important point (which it does stress) is that the poses were usually those that could be held for a long time, without discomfort, to allow for the slow operation of the 8x10 cameras they used. And it was quite common to shoot two dozen or more 8x10s at a single session.
