What is the difference between Ilford Rapid Fixer and Ilford Hypam Rapid Fixer?
I normally use Ilford Rapid Fixer CAT 198 4583 to fix B&W T Max sheet film after Rollo Pyro development or Kodak Polymax VC fiber paper after development. Some how I mistakenly received 5 litres of Ilford Hypam Rapid Fixer CAT 175 8285 in my last supply order. I haven’t found any difference in reading the instructions. Is okay to make this substitution for my needs or should I send this back?
Thanks for your help.
