This is a soft-working, fairly rapid negative developer, producing good detail in the shadows, and is thus useful for negatives which have been under-exposed. It is employed to advantage when the subject is very contrasty (against-the-light shots, portraits with contrasty lighting effects, etc.), or when the film material in itself tends towards contrast (finegrain films of low sensitivity). As compared with similar soft-working type finegrain developers, this formula possesses the advantage of not requiring additional exposure, although it is not a special finegrain developer.

Dilution: For normal purpose dilute the stock solution 1:2 with water, and for very soft gradation 1:4.
Time of development: The image builds up quickly, but with soft gradation; it is fully developed in 5–6 minutes. If development is prolonged the contrast will be increased.
