Toning Prints 119 and selenium � sepia � gold. 1 This latter combination in particular can yield either very colourful images or extremely subtle nuances to infl uence the viewer’s response. Successful multiple toning with these toners relies on two facts: First, each of these three toners works successively through the tonal values of the print, rather than toning all the tonal values at the same time and the same rate. Selenium works “bottom up,” in other words, it starts toning the darkest areas of the print fi rst, works on up through the middle values and reaches the highlight tones last. Sepia bleach starts in the highlights and works “top down” to reach the shadows last and the sepia toner, which follows the bleach stage, tones only the silver that has been bleached. Gold toner also works “top down”—this is more relevant when duotoning gold with selenium at opposite ends of the tonal scale, but less relevant when gold toning after sepia to change the sepia colour (see below). Secondly, with one main exception, the silver that has been toned by one of these archival toners is stable and is left unaffected by almost any chemical used subsequently. The one main exception is that when immersed in gold toner, sepia-toned silver does change color towards salmon/orange/red, depending on the paper emulsion and the way the sepia toner is made up. The signifi cance of these two facts is that a print can be “split toned” 2 with one toner—toning just part of the image tonal scale. In the case of selenium, this might be just the darkest tones, or dark and mid-tones. In the case of sepia, it could be just the lightest of highlights for very subtle effect, or down to the mid-tones for obvious impact. In either case this leaves the print part-toned with the untoned silver still being “up for grabs” by a second toner. Selenium � gold will, with warm-tone and lith prints, give an attractive brown/blue duotone. Selenium � sepia will give either two shades of brown with warmtone papers, or one of the many sepia hues on top of contrasting eggplant purplish brown shadow tones with a neutral/cold tone paper. If gold toner is then used as a third stage, the sepia tones will begin to shift, not towards blue but towards the red/orange/salmon range and the degree of this shift is dependent on toning time, so great control is possible to give hues from just a hint of sunshine to strong colour. If the mid tones are left as untoned silver, beautiful tri-tone effects are obtained. 3 NOTE: Prints should be well washed between toning baths and in particular acidic prints (for example, from direct gold toner, acid stop baths, etc.) can stain if transferred straight to selenium without being well washed, or put through alkaline hypo-clearing agent. 1 This description refers to the widely available single-bath “off the shelf” toners, not necessarily to some of the many other formulae described in this book. 2 Some workers use the term “split toning” as I have here, using a single toner, but also use it to indicate that two or more toners have been used. To avoid confusion I prefer to refer to the latter as duo-toning or multiple toning, rather than split toning. Be aware that more than one interpretation is in use. 3 Examples of these and many other color effects are found in The Photographer’s Toning Book, see the Bibliography at the back of the Cookbook.
