FX-39 is based on Willi Beutler´s formula for Neofin Red, but was further developed by Geoffrey Crawley. Makes very good use of the film’s full ISO-rating. It’s possible to double the films ISO by adjusting the development times. FX39 can be used in various dilutions in order to develop low-sensitivity films with at least 6-minutes developing time. Especially good for films up to 200 ASA.
 

Well suited for school-photography because of the high equalizing power, low toxidity (no GLS labeling necessary) and easy of use (liquid concentrated one shot developer).

 

Standard dilution is 1+9 used as a “one shot” developer.

At 1+14 the time should be multiplied by 1.5 and at dilutions of 1+19 develop for twice as long as with the standard dilution.
