Like photography itself, toning is a culmination of artistic and
scientific processes. This guide explores the techniques photographers
can employ to extend the longevity of black-and-white prints, improve
contrast, create an antique appearance, or add electrifying color. Using
minimal, readily available equipment, photographers can learn to control
variables-paper, dilutions, and toning duration-to create repeatable
results. Duo-toning, masking sections of images, and safe handling of
chemicals are discussed.
