This 5 gallon bottle of Eco Pro Black and White Paper Developer is a liquid developer designed to meet the needs of photographers who enjoy toning prints. The developer produces rich black tones and bright, neutral whites. It works especially well with warm toned paper but will deliver great tonality with both cold and neutral toned paper.
With most papers, prints processed with this developer will offer the widest range of tone (hue) shift when toned with toners such as selenium, sepia and polysulfide (brown)
This is an avid toner's choice, who seeks creative effects while securing rich shadow density
Formulated entirely with low toxicity chemicals
Dilute 1:9 for most applications, and 1:14 when greater control or economy is important
