I had a mishap where my agitation got interrupted by losing the little twisty pin that goes into the tank to rotate the reels. Instead I relied on just rotating the entire tank. Not ideal, but I had already poured the developer in.
Is this a likely cause of streaking?
At the same time, I was dealing with near exhausted fixer. Is that ever a cause for streaking? I can't imagine it would be, but I'm not sure.
This is just out of curiosity. I did get a roll of film streaked, but not beyond the point it cannot be printed. I now realize the importance of consistency of keeping chemicals fresh, and agitation patterns.
Film was FP4+ @ EI 250 in Diafine two bath developer (fresh), and alkaline fixer from Fine Art Photo Supply (which normally clears a film strip in about 1m30s, and now took upwards 2m30s to do that).
Thankful for insight,
