Hi
I'm about to try my first batch of Ilford Perceptol with HP5 400. But I'm having real trouble, for some reason, understanding their time-temperature correction graph.
All the times given on the inside of the pack are for 20 degrees...and the compensation graph might as well have been written in Chinese for me.
Does anyone know what HP5 at 24 degrees would be? I can't find anywhere on the net that mentions it either, so any pointers would be great! :bang:
