Once camera assistants have learned and practiced the rules of their job, they can then begin to explore and test their limits. Stressing theory as well as hands-on experience, Optics and Focus for Camera Assistants melds technical knowledge and skills with technique and attitude to provide key information on one of the most vital parts of a camera assistant's job: focus. Assistants will learn how to make themselves invaluable on the set by being able to apply theoretical approaches to problem solving, allowing them to extrapolate from theory to any practical situation, as opposed to following cook-book style solutions. The book also stresses enhanced techniques for greater speed and precision in routine equipment-handling procedures. In addition to covering such important topics as diagnostic optics for use in the field, fundamental and advanced estimating and focus techniques, and depth of field, Optics and Focus for Camera Assistants also offers essential information on how best to be mentally and physically prepared for the job.
