Results with AristaPan 100

Film Characteristics

  • Grain: Fine grain structure typical of 100-speed film
  • Contrast: Normal to slightly high contrast tendency
  • Tonality: Neutral with excellent midtone separation
  • Shadow Detail: Excellent retention with this developer combo
  • Highlight Detail: Smooth rolloff, no harsh clipping

What Worked Well

  • 4:40 timing provides perfect density for AristaPan 100
  • Temperature consistency prevents reticulation issues
  • Gentle handling preserves the soft emulsion
  • Measured by weight ensures repeatable results

AristaPan 100 Specific Notes

  • Soft emulsion requires gentle handling throughout process
  • High contrast tendency - watch for blown highlights in bright scenes
  • Responds well to D-76 type developers
  • DO NOT squeegee - emulsion damage risk is high
