Good luck on your project.

Im working with HP5+ developed in D76 1+1 for 11:30 mins. at 20 C. I made a roll with the exposure meter set at 125 ASA, thinking in the reciprocity failure. It is still washing, but, in an eye inspection I found it weak. Ill measure it tomorrow when its dry, then Ill know if I have to give longer exposures or give an stronger development, or both.
