Developing Plus-X, and others
Progress...!
Of the five rolls of probable color reversal film, one had the leader still exposed and it had "7 gone" written on it on pencil - so it seemed like the obvious one to try as a test.
I loaded it into a tank, and cut off a portion to test by dropping small cut-offs into HC-110 B at 1-minute intervals. Looking at the emulsion side, I reckoned on between 6 and 7 minutes should be about right. But something curious happened - the non-emulsion side went very black, having been grey to start with.
Then I remembered that this old reversal film originally required a few first development steps followed by a reversal exposure - so maybe the black reverse side was the reversal layer getting developed? (And it's coming back to me more - the film was made by 3M)
Anyway, I developed it for 6.5 minutes, and it has images! It's fixed and washing now, and the images are pretty faint and low contrast, but they're clearly there - and after around 40 years I'm amazed and delighted to see anything at all 😀
There's no blackness on the opposite side, so maybe my speculation that it was the reversal layer was right.
On first inspection while wet, the base fog doesn't look too bad at all, so I think I'm safe to do another roll with a longer development time.
