I have another book to add to my recommendation list; Bryan Peterson, author of the well-regarded Understanding Exposure, wrote another volume for the series -- Understanding Flash Photography.
Having now read through this book completely, I'll add one caveat to my recommendation: Bryan Peterson needs to study the concept of diffusion more closely.
In several of his examples he says he wants "soft light" and so he holds a diffusion panel up to his flash...right up to it, or at most just a few inches away. That won't give soft light, and his example shots show this; they don't look any softer to me than what could be achieved with a flash alone.
Soft light requires the light source to be relatively large compared to the subject, and holding difusion material right up against the flash head does nothing to enlarge the source; you need to have the panel away from the flash so that the light can spread before hitting the fabric.
I think my next project is going to be a tutorial on this topic, with side-by-side examples using -- and misusing -- popular modifiers like Fong Domes, Sto-Fens, Lastolite panels, etc., and showing the way many people are just wasting their time and money with them by not understanding how they work...or don't.
