Photographic Exposure Calculations and Camera Operation
Michael G. Prais, Ph.D.
BookSurge Publishing, North Charleston, SC, 2008. 324 pp., 49 figures and 40 tables, 9x7".
This authoritative work provides a thorough examination of exposure calculations in support of composition, the myth of 18% as midtone, exposure meters, photosensitivity (film speed) of both emulsion (film) and solid-state (digital) media, spatial resolution, dynamic range, the photosensitive exposure range, exposure compensation, the Sunny f/16 Rule, the Zone System, APEX calculations, ISO/ANSI standards documentation and depth of field calculations. In addition to explanations of these terms and their connections, this book offers a very general exposure equation, tables of representative and exact stop values, extensive diagrams for and examples of exposure calculations, very general depth of field equations and extensive depth of field tables that make it useful as a supplementary text in a course on photography or as a field guide.
This book is a critical study of exposure and other camera operations that appear in most if not all photography textbooks and other instructional books. A variety of myths have become associated with exposure calculations, exposure meters, depth of field, and the like, and this book shows that and how these myths are untenable.
