Adox FX-39 Type II Film Developer, 500ml

This one-shot, high definition developer is perfect for bringing out exceptional detail and extreme sharpness from your negatives.

Based on the Beutler Formula for Neofin Red, it was originally formulated by Geoffrey Crawley for Paterson Photographic but was withdrawn in 2012. We're pleased to announce its return with it now being made by Adox in Germany.

FX-39 Type II is closely related to Acutol but specifically developed to exploit the advanced silver halide grain technology in films such as Ilford Delta, Kodak Tmax or Fuji Acros. It makes very good use of the film's full ISO-rating and is possible to double the film's ISO simply by adjusting the development times.

At 1+19 dilutions, twice the normal development time applies, giving you a valuable compensating effect with extra shadow detail and the ability to cope with high contrast subjects.

We especially recommend it for films up to 200 ASA.

Standard dilution is 1+9. At 1+14 the time should be multiplied by 1.5 and at dilutions of 1+19 develop for twice as long as by standard dilution. The new version features better keeping properties and is less sensitive to low temperature shipping.
