Film developing notes

The below film developing notes are meant as a reminder for myself. I’m posting them here to also share with others. Times have been determined by doing a maximum black for minimum time test on fiber paper in my darkroom.

  • Exposure 400 ISO
  • Xtol 1:1 distilled water at 20 degrees Celsius
  • 12:30 mins
  • 1st minute constant agitation 
  • 3 inversions every minute
  • Citric acid stop 30 seconds
  • Quick Rinse
  • Alkaline fixer 5:00 minutes same agitation as above
  • 5 min wash in Paterson Tank
  • Let sit for 30-60 minutes in tap water
  • Driwell or Photoflo then hang to dry.
