ABSTRACT
Toning adds color to a silver-based image, such as a black-and-white photograph, enlargement emulsion print (see Chapter 13), Van Dyke brown print (see Chapter 8), or graphic arts film transparency (see Chapter 5) by immersion in, or the selective application of, chemical agents. This process can be performed in ordinary room light as an added step after the print has been completely processed and thoroughly washed. Time, temperature, age, dilution, and the type of darkroom chemicals used for processing the print, as well as the type of paper (silver bromide papers usually are cool blacks, while silver chloride papers are usually warmer blacks), will cause variations in color and often affect the finished appearance of each toned image. Therefore, consistency in the making of the original prints and toning afterward is imperative if uniform results are desired.
