thank you Simon, for looking into this for me. Unfortunately, I did not include the batch number, but I feel it doesnt pertain to this particular matter, since the problem has repeatedly happened with different emulsion batches.
Simon - I may send you a sample of some 120 film, either FP4, or one of the Deltas. Mine always come out with some kind of non-glossy finish, not that it seems to bother anything.
I'll wait till I shoot a roll that I still have the box for, and include it with the film.
I did send samples to Ilford and they looked at them under a microscope and it appeared to be a form of reticulation on the base side. They informed me that I should not presoak the film, which I was concerned about, but I went ahead and they were right, the problem went away. The base side now looks very shiny.
Yes I just went through the same problem last month with the Hp5 8x10 and solved it by not pre soaking, which I do with everything.
Now I am using some 8x10 Fp4 and without a pre soak I got mottling. I went back to pre soaking and with Fp4 see none of the problem I had with Hp5.
