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.
