Fotospeed Toner for Black & White Prints - Blue/ Makes 1.2 Liters

Fotospeed Blue Toner consists of three concentrates that are mixed to a single working solution.

This iron blue toner gives a deep cobalt blue to an electric blue when using the techniques descibed in the data sheet (included with each product), many variations are possible, and can also be used on film.

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.
