Kodak Professional Rapid Selenium Toner is a classic method for adjusting the look and coloration of prints, as well as for increasing print stability and archivability. It is suitable for both resin coated and fiber based black & white papers, and its effects vary based on paper type, tone, surface texture, and toner dilution. When used with warm-tone papers, it produces cool, chocolate brown hues; with neutral-tone papers, it produces purplish brown tones; and with cool-tone papers, little to no color change is expected. Rapid Selenium Toner also helps to extend the apparent Dmax of prints, with the ability to produce a richer range of tones in the shadow areas. Additionally, this toner can also be used with black and white films, where it converts the silver image to silver selenide for increased stability and also slightly improves contrast.
This is one 32 oz bottle of liquid toner and can be diluted to varying degrees depending on application and paper type.
