PERCEPTOL is an extra fine grain film developer producing excellent image quality. Designed for use when very fine grain negatives are required but a decrease in film speed is not important. It exploits the superb grain structure of ILFORD medium and slow speed films DELTA 100 PROFESSIONAL FP4 Plus and PAN F Plus and produces significantly finer grain in ILFORD fast films DELTA 400 PROFESSIONAL HP5 Plus and DELTA 3200 PROFESSIONAL compared with a standard fine grain developer.
