Universal Monochrome Film Developer – Precision Fine-Grain Formulation, Broad Processing Method Compatibility (Spiral Tanks, Dishes, Trays, and Motorized Rotary Processors), Concentrated Liquid Chemistry with Recommended 1:9 Dilution Ratio, Yields 5 Liters of Working Strength Solution, Full Dynamic Range and Sharp Acutance Retention (Fresh Stock / Mint Condition)
Kentmere Black and White Film Developer is a professional-grade liquid concentrate engineered to deliver clean acutance, controlled grain structure, and a smooth, expansive grayscale tonal range across a wide variety of black-and-white negative film stocks. Developed for film enthusiasts, darkroom lab technicians, and fine-art photographers, this versatile chemical developer delivers consistent, repeatable results with dependable shadow detail and controlled highlight density.
Designed for adaptable darkroom workflows, Kentmere Film Developer is suitable for manual daylight inversion tanks (such as Paterson or stainless steel spiral tanks), open dishes, flat trays, and continuous agitation automated rotary processors. The concentrated liquid formula mixes quickly with water at a recommended standard 1:9 dilution ratio (1 part concentrate to 9 parts water), producing 5 liters of active working strength developer from a single bottle. The clean-working liquid formulation eliminates the need to dissolve dry powders, ensuring rapid preparation, dust-free mixing, and stable, repeatable development times for both student and professional analog darkrooms.
