  3. Re: Modifications to Kodak 8x10 hangers for even development of double-sided X-Ray fi

    I never had a temperature-controlled tank line, just Cescolite plastic 4X5 tanks and Kodak hangers. I kept the lab at 68* in winter and 75* in warmer months.
  4. Re: Modifications to Kodak 8x10 hangers for even development of double-sided X-Ray fi

    Looks to me as though it was hit with a light leak in the tank, right down the center of the reel. Inspect the light seal in the lid of the tank you used.
