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.
