To produce reddish brown tones in warm tone papers, dilute Berg Selenium Toner 1 part toner to 3 parts of water (1:3) and immerse paper for 2 to 10 minutes. Other papers may give little or no color change.

To avoid color change, but protect the image and increase Dmax, dilute 1 part toner with 10-30 parts of water, and tone for about 2 to 10 minutes.

After toning, wash thoroughly to achieve maximum archival protection.
