Ilford selenium toner - Extending darkroom options on printing black-and-white images to further levels of artistry is a new selenium toner from ILFORD Photo.

Even today, selenium toning is a sensible precaution for prints that are on continuous display.

Selenium toners are single solution toners that partly convert the original silver image to silver selenide.

The degree of toning can be varied by changing the toning time or solution dilution.

With Multigrade IV RC DeLuxe, very little colour change results in selenium toners, but it tends to darken the shadow areas of the prints, and tint them purple. The highlights do not change in density however.

Warmtone papers are very responsive to selenium toners. Toning Multigrade Warmtone papers with higher dilutions (e.g. 1+10, 1+20) of selenium toner - gives a slight cooling of the image tone and a shift in hue towards red.

Used at lower dilutions (e.g. 1+3, 1+5) - a purplish brown can be achieved.

Below are the key points and methods associated with selenium toning.

Selenium compounds are extremely toxic, so preparing the solutions from raw materials is hazardous.

ILFORD therefore recommends that you use a proprietary brand - such as Kodak Rapid Selenium toner (this is diluted 1+3 for usage). Other commercial selenium toners include Berg Selenium, Fotospeed SLT20, and Maco Selenia.

Selenium safety

Always take extreme care when using selenium toner. Wear gloves and goggles, and never heat the solution as the fumes it gives off are poisonous.

Selenium is hazardous to wildlife - as it is also to human health. In many regions, it is illegal to dispose of the spent solution by pouring it down the sink. Before using selenium, contact your local authority for advice on safe disposal of selenium toner residues.

Prints toned in selenium toners generally have higher density and contrast than untoned prints. They also have a higher maximum density.

The toners are normally single solution toners - partially converting the original silver image to silver selenide.

With selenium toner, there is no bleaching step. After processing and thoroughly washing a Multigrade IV RC DeLuxe print, immerse the print in the selenium toner for between 3 and 10 minutes - depending on the end tone required. (Note too, the tone can also be altered by controlling the dilution of the toner).

As toning causes subtle changes, it is sensible to keep an untoned print nearby for comparison purposes.

Maximum protective effect is achieved with Multigrade IV RC DeLuxe paper - in about 4 minutes.

One of the major benefits of using silver photography, and processing prints in chemistry baths, is the degree of control which can be exerted on the finished product. This is never more obvious than when extending the purity of tone and line inherent in black-and-white photography with the use of toners. Not surprisingly, therefore, it is a field into which Ilford Photo has put a great deal of research and development.

Due for availability in summer 2006 is the first of what will be a full range of colour toners from Ilford Photo - Ilford Harman selenium toner - which takes the artistry of a monochrome print to perfection. This high quality formula is straightforward in use and has several advantages in addition to emphasising the versatile tonal range of black-and-white prints.

The degree of effect which any toner will have on a print depends on, firstly, the dilution of the solution; secondly, the time the print is immersed; and thirdly, the type of paper being used.

The Ilford Harman selenium toner will be supplied as a ready prepared liquid, so there are no particular toxic concerns, and is recommended to be used at 1+10 dilution for optimum results. The time required will depend on the tonal quality of the print, but around 5 minutes is a general guide.

This mix will enhance the maximum density (Dmax) of the blacks, and change the image tone. The toner absorbs any olive hue present, and pushes shadows towards a purplish black finish with no discernable effect on the highlights. The effects will be most noticeable when using Multigrade Warmtone papers, but more subtle on harder papers such as Multigrade IV.

The reaction of the selenium on the silver halide (AgX) of the print hardens the adherence of the image to the paper, thereby improving its stability, permanence and archival properties as well as defining its appearance.

Altogether, Ilford Harman selenium toner will provide the finishing touch which turns an excellent black-and-white picture into a photographic masterpiece.
