Practical effects (contrast, fog, maximum density, and scale index) on the characteristic curves of Ektacolor paper were found for variations in the concentrations of sodium carbonate, potassium bromide, 6-nitrobenzimidazole nitrate (Kodak AF-71), color developing agent (Kodak CD-3), pH, and citrazinic acid (CZA) in an Ektacolor developer used on the Kodak model 11 drum processor. The effects of pH, citrazinic acid, potassium bromide were found to be significant while the effects 6-nitro benzimidazol nitrate and CD-3 were significant only in isolated insidences.
