For sharp images with excellent contrast control.

FX-39 is a legend.
For more than 40 years Geoffrey Crawley has readjusted and optimized different developer recipes and created this masterpiece in the heydays of film. FX-39 is based on Willi Beutler’s Neofin Rot formula, but was improved in all parameters. For 10 years ADOX has been improving this formula.
FX-39 is a compensating developer, providing excellent detail rendition, sharpness and resolution. The effective film speed is high. The compensating effect can be well controlled in a very wide range by variations in dilution. The compensating effect can be precisely adjusted to the subject contrast and film type. There remains only one reason for not using FX-39 exclusively and that's for the absolutely finest grain. If you want the finest grain possible then developers like Adox Atomal are the optimal solution. FX-39 harmonizes excellently especially with all low and medium speed films. In the ISO 400/27° class the best results are obtained with Kodak Tri-X, Kodak T-Max 400, Ilford Delta 400 and Fuji Neopan 400. If needed FX-39 can also be used for increasing film speed by 1 stop (push processing).
