Liquid Light on glass

  1. You did fix the plates, right?

    Development process consists of:
    Water rinse or mild acid stop bath for approximately 1 minute.
    Fix - time depends on type of fixer.
    Water wash - 20 to 30 minutes in running water or multiple changes of fresh water. A longer wash doesn't hurt.
    Air dry.

    The develop, rinse and fix stages should all be at the same temperature. As ideally should the wash stage, but the temperature of wash water can be gradually reduced to that of your cold-water source.
  2. Yes, I believe so. The last two plates that I did have maintained their color/tone thus far and the main difference was a much longer bath time.
  3. Which bath? Fixer or final wash?

    The only way that the plates can darken with a relatively short exposure to light is if they still have unexposed and undeveloped silver salts remaining. And that means the fixing wasn't sufficient. Due to insufficient fixing time or exhausted or weak fixer.

    Insufficient final wash can cause a sepia tone or blotchy discolouration of the image, but not darkening of the clear parts of the image. Plus this usually takes some weeks, months or even years to show itself.

    In any case: Exposure to sunlight or UV after processing isn't a good idea. Processed plates/film should be kept in dry and dark conditions.
