I accidently processed this roll in partially exhausted developer, and when I pulled it out from the fixer, I knew it immediately. At the time I was thankful and hopeful, because the developer had at least partially processed the roll(s).
In hindsight, however, I would rather have had the roll completely destroyed, because I can see the images, the compositions, and I know I had some decent shots.

The one above is about the best I can pull out of the roll with this scan and scanner. I recently picked up a new scanner, so I'll probably give the roll one more effort. I'm still hopeful.
BTW, I've not made the same mistake again.
