Barr writes with a thoughtfulness and a clarity that makes this the one book I reliably carry to set. Barr manages to be both a technical educator and a spiritual guide all in one. A balanced left/right brain approach to the specific requirements of on-camera performance in every conceivable situation. This includes a perfect compliment of photos which serve to reinforce the lessons. He's especially amazing when discussing aspects of professional acting, like continuity and emotional transitioning, you might otherwise be hard-pressed to learn in classes. http://www.amazon.com/Acting-Camera-Revised-Tony-Barr/dp/0060928190
