Agitation was continuous and vigorous throughout development and fix - about 100 seconds for dev, 60 for fix. (RC paper). Both developer and fix were mixed fresh right before use.
I'll try it again tomorrow with twice as much developer and the same neg. If the problem disappears, I'll know not to be so tight-fisted with the dev in the future.
Well two suspects come to mind right away. First is marginal developer. After being used for some prints, getting closer to exhaustion would make such problems more likely. The other is agitation during the development process. Just like washing, rocking of the tray keeps pockets of what might best be described as developer that is less than ideal next to the same spot on the print. Movement in the tray should help keep the chemistry more consistent, just as movement of the water in a wash keeps diluting the fix that remains in the print.Jeffrey Thorns <puresilver@xxxxxxxxx> wrote: Let's say, hypothetically, that a photog were to mix up some LPD stock solution 1:1 with water, and use only about 24 ounces in an 11x14 tray. (Obviously, this photog is confusing thriftiness with being a cheapskate.) Then he puts several 11x14 prints thru. Near the end of the session, some of the dark, uniform areas of the prints were showing wavy, slightly higher-density lines. (These lines did not show up on earlier prints, and they vary from print to print.) Could this be an effect of byproducts of the development process?
