I'm desperatly trying to straighten the boldly s-shaped curve of the Retro 80s. So far i've tried Perceptol 1+3, Rodinal 1+50 an HC110 dil. H.
With e.g. HC110 for 10 min with 1 inversion each 60 sec i'm getting Zone II logD 0.03 , Zone V logD 0.48, Zone VIII logD 1.58 at EI 64. The results with the other developers are quite similar.
So why bother with this film? Because it would be a nearly grainless IR film with high resolution.
Has anybody found a developer that would provide a 'normal' (i. e. Zone II logD 0.25 Zone V logD 0.7 and Zone VIII logD 1.3) curve with suffucient film speed (EI 50 to 100)?.
