Dilute 1:1 and develop for about 2 minutes. More bromide may be added if warmer tones are desired. For a softer print, dilute 1:3. To increase the warmth, add bromide up to double the amount in the formula (this may cause a slight green cast with some papers).

Similar formula as proprietary Kodak Selectol.
