Fotospeed Copper/Red Toner is a two part liquid concentrate mixed to a single working solution. The shade of copper/red is determined by how long you keep your print in the toner.
Warm copper shades to cherry reds can be produced using the techniques described in the enclosed instructions.
Prints should be 15% darker than normal.
Fotospeed toners have been specifically designed for the toning of black and white silver based emulsions.
The toning process involves the conversion of the black silver within the print to another metallic compound. When correctly toned, the image will be chemically stable.
Toners such as Selenium and Gold are ideal for archival permanence techniques.
Toning techniques are carried out after the print has been fully fixed and washed and are therefore performed under normal daylight conditions.
Toning is very much in the creative domain of the user. When toning it is important to observe the shift of color in the print.
