Strange developer color action due to nanopowder farming ?
20 years ago, someone gave me lots of powder chemicals. I tried to identify from their crystal shapes and I developed 60 rolls of 120 Agfa Isopan. One night , developer turned to pitch petrol color after 12 hours, it turned to deep red and 6 hours later gone transparent.
I opened a thread and no one answered the question.
I asked to the photo engineer and he said dyes and oxidation.
I found nano powders especially silver goes to deep reds to green and lost their color in liquid in time.
Question , Had had I been farmed nano powders ?
Same happens to color photographers and get pink cast.
