nostr:npub1sdms0942fed02rrv0s4jzg5mf803lflvxl905d04nj37a2autzvqj9wzn8 Thanks for your suggestion. I don’t think it is caused by a binding spool though, as too much film is being wound through, rather than not enough.

I do like your idea of sacrificing a roll of film and watching what happens when you wind on. So obvious, yet I didn’t think of it! I have half a dozen rolls of Ilford FP4 with Ilford measles.Perfect for testing purposes like this. I shall wait to see what the Kamerastore will say on Monday. But definitely one to remember 👍.
