The Berg Brilliant Blue Toning Concentrate Solution is used in ordinary room light to convert black and white prints or films to a rich, deep blue color. The toning result depends mainly on the time of treatment and the nature of the black and white material. All silver-based black and white images may be toned; however more rapid toning occurs with warm-tone papers.
