In this textbook, which was written for the professional photography student, both photographic theory and practice are thoroughly explained. The author examines the principles of light and the properties of lenses and gives a detailed evaluation of camera movement, camera shutters, and the camera as a whole. He outlines the manufacture and properties of light-sensitive materials and discusses individually the multiplicity of effects possible with variations in filters, lighting, and exposure. Complete explanations are provided for the various techniques used in developing, printing, and finishing the photograph. In the final chapter, the visual analysis and interpretation of a subject is discussed in relation to the demands of professional photography and practical experiments are suggested to illustrate some basic concepts. Each chapter is sectionalized with subheadings and includes a brief summary and suggested examination questions. A large number of diagrams and photographs illustrate the text. (JY)
