“Toning”and Colorizing Monochrome Images



The image color of even a conventional black and white silver print is rarely black, white and grayscale shades. It may be warm (golden) or cold (blue) neutral or toned (sepia, magenta.) Over many years print makers and chemists developed paper and developer combinations, as well as after-printing toners, to add additional color to monochrome silver prints. For example, using a warm-tone paper and warm-tone enhancing developer, such as Selectol Soft, could alter image color. This yielded brownish blacks and creamy whites. A cold-tone paper could be developed in Dektol and after fixing toned in a mild dilution of rapid selenium toner for added “snap”, a harder bright white/deep black effect.

Silver papers were and are toned sepia, brown and even blue for various image effects, as well as for archival reasons. The image color of a monochrome print is one of the keys to its beauty, one that a discerning eye will always appreciate. If you ever wondered where all the terminology around black and white prints in the digital realm stems from you need not look further than the black and white chemical darkroom. In fact, it seems the prime aim of many manufacturers, and indeed many printmakers, is to make a digital inkjet print look as close to a silver paper print as possible. Ironic.

Yet, given the irony, the ability to emulate and even expand on potential image color possibilities in the digital darkroom is very wide. Anyone who has struggled to maintain consistent image color throughout an edition or portfolio, or who has tried a variety of toner dilutions to get an image just right will especially appreciate it. The ink and paper options and the processing potential available today are one of the most exciting elements in expressive digital printing.

Study of prints made by photomechanical means other than conventional darkroom methods also reveals the amazing image color possibilities of the photographic image. Platinum, palladium, cyanotype, Van Dyke Brown and even photogravure show very seductive image color effects. Some of these arcane processes are kept alive by a dedicated core of artists, and are often referred to as alternative or personal processes. While digital ink mixing cannot hope to obtain the patina of these images (the surface characteristics) they certainly can emulate the look and visual feel. They do this without mixing often-dangerous chemicals.

In addition, there are options for adding a dash of color to a black and white print for visual interest, or even applying color to make a print look like an old hand colored postcard or portrait. Handcoloring, first used to add color to photographs before color film and paper was readily available, is a fun way to make your own color interpretation on a black and white scene.

In the next series of posts I’ll discuss some of the options and processes to use.
