    Hello all

    Long time lurker, first time poster here.

    Am currently experimenting with some expired Agfa Copex HDP13 (not Rapid) 16mm microfilm bought very cheaply on a certain auction site. I think this stuff has a notional ISO of 12 or 25 or so. I'm cutting it up and reloading 110 cartridges then shooting them in a Pentax 110 Auto mini-SLR. Being a 110 camera, it has no ISO dial, but only the "high" and "low" notched 110 cartridge system. "Low" is approx 100 ISO so that's what I've had to use for this film.

    Now with several carts ready to develop I'm wondering what dev to use for them. I'm after the classic high contrast or lith type result. Developers I have to hand are Rodinal, Tmax, D76, HC110 and some Rollei LHC.

    Any ideas?

    cheers, phil
