Response to How to develop an old B/W film

from Don Karon (kc6d@arrl.net)
There's probably little latent image left after all these years. In 1974 I developed some film that was exposed five years earlier. Got only a faint image from the most exposed regions, the rest of the frame was clear. Thermal effects or quatum wiggling or whatever seems to cause the exposed halides to revert to ground state.
