This book demonstrates a uniquely economical, efficient and accurate testing procedure based on sensitometric principles. It shows how test data can be used in several exposure development control systems. Phil Davis provides a thorough explanation of photographic material characteristics. Features Appendix with numerous important formulae; Instructions for specialized developing tubes; Directions for creating a unique spot meter unit, an inexpensive substitute for an expensive densitometer.
Filled with solid info on black and white sensitometry, but a bit disorganized in its presentation. I would recommend reading The Kodak Sensitometry Workbook first. I also have some issues with Davis' understanding and modeling of flare effects on film.
