In their familiar easy-to-read style, the authors (who have earned their living by taking pictures all over the world) provide a wealth of information on the theory and practice of exposure, whether on location or in the studio; information which is always applicable, regardless of the size of the reader's budget. They begin by looking at what constitutes the 'perfect exposure', and then move on to the theoretical basis of exposure determination; the different types of meters available; metering techniques; and how to apply those techniques to a wide range of subjects. There are also chapters on printing (in monochrome and colour), and appendices on the Zone System, using Polaroids, and useful rules of thumb. Over 200 pictures complete the story, with detailed explanations of how exposure readings were modified to achieve the desired results.
