I have heard that suggested somewhere - don't remember where now.
However, it was suggested in rain, snow - bad weather situations -
this was not bad weather.  Is there an archive to this list?  Now that
I think about it, I remember those postings; but I also belong to the
pinhole list and I think I may have deleted some prematurely.

I don't get them very frequently.  I use D76 stock solution - premixed
in bottle form.

I have suspected the batch idea myself.  With this recent pinhole
problem, I developed 3 rolls of film together.  Only 1 roll had the
problem.  Of the images on the roll, only approx. 5-6 images had the
problem (the best image being one of them.)
