    Someone gifted me a few rolls of Shanghai Seagull 100 PAN b/w 120 film...best I can remember it also says GF3.

    I have spent some time trying to find data to no avail.

    Any numbers for reciprocity correction?

    Thank you

    Oops, it's GP3.

    It's probably accurate to say it'll be close to Plus-X for reciprocity failure. I've used the Plus-X figures for Fomapan with good results, and it seems most if not all conventional grain films have about the same level of correction -- Tri-X, FP4+, etc. I've heard exaggerated claims for APX 100 and Efke 25, but never seen much proof of them.

    Your'e very welcome! Do post the results, if/when you get some. And for dev time, I'd probably give the first roll 19 minutes in HC-110 G, agitating continuously the first minute and then 5 inversions every 3rd minute (same as I give Pro 100, though Fomapan 100 will be a little overcooked with this much development; I give it 16 minutes instead).
