PERCEPTOL is an extra fine grain film developer which gives excellent image quality. It is designed for use when very fine grain negatives are required and a decrease in film speed is not important. It has been specially formulated to get optimum results from high resolution lenses. It exploits the superb grain structure of ILFORD medium and slow speed films, 100 DELTA 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.
PERCEPTOL produces excellent results with any lens/film combination and is therefore ideal when texture and definition are critical - negatives developed in PERCEPTOL are capable of producing sharper and better quality enlargements that those produced using a standard fine grain developer.
