Book excerpt: Studio and outside broadcast is often done with more than one camera and has its own distinct discipline and operational procedures. Many camera operators now start with single camera operations and have little or no experience of the skills required for multi-camera operation, whereas it used to be the other way round. This book prepared newcomers to multi-camerawork and the techniques required to produce professional results. Studio and Outside Broadcast Camerawork is a revised edition of Multi-Camera Camerawork, including new material on widescreen shooting and an update on BBC (and worldwide) policy of 'shoot and protect' for dual aspect ratio format production.
