Dev Times for Pre ‘Plus’ Ilford Films and Neopan SSS

I’ve just picked up some old 120 film, all well out of date and discontinued formulations.

Where can I find dev times for HP5 and FP4 (expired around 1990, before the move to the ‘plus’ version). I have searched, but assumed most results referred to the current versions, HP5+ and FP4+.

I also have a few rolls of Fuji Neopan SSS 200, expired in the late 70’s. This appears to be long discontinued, I couldn’t find any dev references to it.

Is there anything I should do to reduce fog/counter any other issues with old film?

The developers I have are HC 110, Rodinal and Diafine.

Thanks for the help!

Dev times for FP4 are the same as FP4+, give a bit of extra time to increase the contrast 15-20%. NeopanSS should be fairly similar.

I have only seen Neopan SSS for sale once in my life, back in the 1970's I bought one roll. along with some Neopan SS. The SS was ASA100 like the current version, the SSS was ASA 200.

Ah. Makes sense. It was before my time.

Still, 100SS is a killer film.
