Unfortunately this test does not investigate the difference between
D76 and ID11.
I thought how to set up a test like this, but can't think of how to
control the many variables of such a long-term test (I like to do it
over 18 months). Film will age over that time, and the exposure
might not be consistent either.
I'm wondering if it would be better to do all the required exposures
at the same time, freeze the exposed film and just pull the
individual sheets out of the freezer as required.
Does anyone know some facts about latent image stability of frozen film?
Considering that labs use frozen control strips for monitoring
chemistry, you would think this would be a viable method. But I don't
recall how long you can hold on to control strips before they expire.
