ADOX HR-50 / SCALA 50 in the reversal process @ Studio13 / Stuttgart

Professional Lab Photo Studio 13 (www.photostudio13.de) has done very detailed tests of ADOX HR-50 / Scala 50 in their Scala BW reversal process during the last months. Result: The experts from Photo Studio 13 are really impressed, since the results of HR-50 in the Scala Process are outstanding. Therefore, Photo Studio 13 is now also offering development of HR-50 in their Scala BW reversal process.

Here is their description of the results of ADOX HR-50 in their Scala process:

  • Speed ISO 50/18°
  • Superpanchromatic sensitization (red is recorded a bit lighter)
  • Outstanding resolution
  • Excellent sharpness
  • Extremely fine grain (only ADOX CMS 20 II has significantly finer grain in the Scala process)
  • HR-50 is suitable for high contrast scenes (great ‚dynamic range‘)
  • Very low value for Dmin (brillant highlights)
  • Very high value for Dmax (deep, ‚rich‘ blacks)
  • Neutral to slightly warm tonality

Pull development for ADOX HR-50:

Photo Studio 13 is also offering a pull development for HR-50 of 1 stop. For this 1 stop pull please expose the film at ISO 25/15°. Resolution, sharpness and fineness of grain are about the same level as with exposure and development at box speed. Contrast is a little bit lower with pull development and Dmax is slightly higher compared to box speed. The differences in contrast and Dmax between box speed and 1 stop pull are very small. ISO 25/15° can be used without any problems, if the situation requires it.

Push development for ADOX HR-50:

Photo Studio 13 is also offering a push development for HR-50 of 1 stop. For this 1 stop push please expose the film at ISO 100/21°. Resolution, sharpness and fineness of grain are almost on the same level as with exposure and development at box speed. Contrast is a little bit higher with push development. And Dmax is slightly lower compared to box speed. The differences in contrast and Dmax between box speed and 1 stop push are quite small. ISO 100/21° can be used without any problems if the situation requires it.
