| The Negative, in addition to a completeworkable exposure-development plan,covers visualization, testing for optimumopacity, exposure meters, pre-exposure,compensating developers, effects of lensflare, reciprocity departure, darkroom pro-cedures, and many other subjects relatedto this phase of photography. Many illus-trations, simple diagrams and charts, tablesand recommended formulas, and detailedcaptions all serve to make this book animportant source of useful information. In this volume Ansel Adams intentionallyreevaluated sensitometric terms in a lan-guage which the non-science-oriented stu-dent will understand. He staunchly sup-ports the determination of exposure byreading the values of light reflected fromthe subject, but not mere "average" read-ings. He shows you how to place the sub-ject brightnesses carefully on the exposurescale of the negative and to develop thenegative in relation to this placement.Adams has really restated the classic prin-ciple of photography, "exposure for theshadows and develop for the highlights,"but with revealing and constructive pre-cision. |
