Beyond the zone system / Phil Davis.

4th ed.

Boston : Focal Press, ©1999.

x, 220 pages : illustrations ; 28 cm

"Beyond the Zone System, Fourth Edition successfully bridges the gap between the well-established science of sensitometry and the popular use of photography as an expressive medium." "Updated to include a new chapter on control of image gradation, Beyond the Zone System, Fourth Edition goes beyond trial and error, and provides a thorough explanation of photographic material characteristics. Both theoretical and practical, this book is essential for anyone who wants to know why, as well as how, the photographic process works. Book jacket."--Jacket.
