The Negative, in addition to a complete
workable exposure-development plan,
covers visualization, testing for optimum
opacity, exposure meters, pre-exposure,
compensating developers, effects of lens
flare, reciprocity departure, darkroom pro-
cedures, and many other subjects related
to this phase of photography. Many illus-
trations, simple diagrams and charts, tables
and recommended formulas, and detailed
captions all serve to make this book an
important source of useful information.
In this volume Ansel Adams intentionally
reevaluated sensitometric terms in a lan-
guage which the non-science-oriented stu-
dent will understand. He staunchly sup-
ports the determination of exposure by
reading the values of light reflected from
the subject, but not mere "average" read-
ings. He shows you how to place the sub-
ject brightnesses carefully on the exposure
scale of the negative and to develop the
negative in relation to this placement.
Adams has really restated the classic prin-
ciple of photography, "exposure for the
shadows and develop for the highlights,"
but with revealing and constructive pre-
cision.
