Precision Darkroom Print Developer – Formulated for High-Quality Black and White Prints, Optimized for Manual Tray Processing, Universally Compatible with Resin-Coated (RC) and Traditional Fiber-Based (FB) Papers, Concentrated Liquid Formula with Recommended 1:9 Dilution Ratio, Yields 5 Liters of Working Strength Solution (Fresh Stock / Mint Condition)
Kentmere Black and White Paper Developer is a professional-grade liquid concentrate formulated to deliver crisp image tone, clean highlights, and rich, deep maximum blacks across traditional photographic darkroom printing processes. Engineered for darkroom printers, fine-art students, and lab technicians, this versatile print developer provides consistent, repeatable development characteristics with smooth grayscale tonal transitions and excellent print contrast control.
Designed primarily for open manual tray development, Kentmere Paper Developer works cleanly with all modern resin-coated (RC) papers as well as heavyweight traditional fiber-based (FB) photographic papers, including variable contrast and graded emulsions. The concentrated liquid formulation mixes easily with water at a recommended standard 1:9 dilution ratio (1 part concentrate to 9 parts water), producing 5 liters of active working strength solution from a single bottle. It offers long tray life, dependable activity, and clean-working properties that resist premature oxidation, ensuring pristine prints from the first test strip to the final exhibition print.
