APPLICATIONS PRINTING IN BLACK & WHITE TONING PRINTS
Gold toning used alone gives blue blacks, but used with sepia toners produces orange-red effects.
Most commercial gold toners are single solution toners. When used on their own, gold toners will shift the image colour of a print to a blue black. However, when used in combination with a sepia toner - they will produce attractive orange-red colours.
The mechanism involves gold metal being deposited onto the silver of the image.
Examples of commercial gold toners include :- Berg gold protective solution, Photographers Formulary Gold 231, and Tetenal gold toner.
Prints toned in gold toners generally have similar density and contrast to untoned prints - the image being used should receive normal exposure and be fully developed.
For detailed processing methods - refer to the instructions supplied with the chosen gold toner.
