Adox HR-Dev for B&W Films ~ 100ml Concentrate

Adox HR-Dev for B&W Films is perfectly adapted to the characteristics of the film material. ADOX HR-dev   straigthens the curve, provides a steeper rise from the shadows and a reasonable light seperation up to zone 9.

The working solutions, which is used to determine the speed and contrast values, have been prepared with distilled water. If harder water is used, the development times must be considerably extended depending on the degree of hardness.

The below mentioned development times for the ADOX HR

-50 are adjusted to reach optimal tonal values, but if you prefer more contrast and highlight seperation, you should develop one minute longer.

When using condenser enlargers, the resulting sensitivities and contrast values are higher, so in this case the development times should be reduced by about 15 %.
