ADOX HR-DEV is a novel special developer for the ADOX HR-50, which is perfectly adapted to the properties of this film material. This is very important for this film because the curve shape is sometimes unsatisfactory when using conventional developers due to the S-shaped curve shape. ADOX HR-DEV straightens the curve, provides a steeper rise from the shadows and a reasonable light differentiation up to zone 9. The working solutions used to determine the sensitivity and contrast values have been prepared with distilled water. If harder water is used, the development times must be extended considerably, depending on the degree of hardness. Sensitivity and contrast values were determined by measuring with a densitometer directly on the developed film, which is similar to measuring under a diffuser enlarger. When using a condenser enlarger, the resulting sensitivities and contrast values are higher, so in this case the development times should be reduced by about 15%. ADOX HR-50 is also extremely suitable for the development of all other SW films and delivers fine-grained and absolutely sharp results with fantastic tonal values. ADOX HR-50 developer is also very well suited for pushing due to its outstanding tonal values. For the Kodak Tri X we have not only tested the nominal sensitivity but also the push sensitivity up to ISO 1600/33°. Even at ISO 1600/33° the tonal values are quite excellent, the highlights remain absolutely moderate, the contrast is only slightly increased at this sensitivity (N + 0.5).
