    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.
