Short story about pyro development.
During the wash step of a BW development made with PMK, one of my students
left his roll for a long time in the water bath (may be five hours or more
...).
When he was back it was almost impossible to see the yellow green stain. One
year
before, we made an extensive study about pyro development and we were
neglectful about the wash parameter.
Perhaps a new way to explore for the mastering of pyro staining ?
In our area (the school is based ten miles east Paris) water is very hard
and wash aid is useless.
Hope this help
