I've more or less standardised on Pyro PMK as a negative developer with HP5 and FP4. It produces negatives that are perfect for making ordinary silver prints, but the proportional yellowish stain acts as added density which is most effective at the blue and UV end of the spectrum. This makes the negatives fine for alternative processes, too. The development times I normally give are 13 mins at 21C for FP4 and 16 mins at 21C for HP5. These times are rather longer than the recommended N times, but I find they're necessary for making prints on Ilford Multigrade with the No 3 filter.
Hope this helps. Derek Watkins ---------- From: INTERNET:pinhole-discussion@p at ???????

I've been using large format pinhole negatives to do alternative process printing. I've been aware for some time of the extent to which I can influence the contrast of a tray-processed TMAX negative by the amount of agitation I provide. I understand that TriX is much less susceptible to contrast control this way, but I've never tried it. I just tried some Ilford HP5 5x7 negatives intended for cyanotypes and palladium printing, and found much less contrast than I expected with what I thought was over-agitation. Any thoughts? _______________________________________________ Pinhole-Discussion mailing list Pinhole-Discussion@p at ??????? unsubscribe or change your account at http://www.???????/discussion/
