I have started using the Pyro PMK film developer formula developed by Gordon Hutchings in combination with Delta 100 and HP5. I am also using variable contrast enlarging paper and I am wondering about the effect created by the yellow pyro image stain which changes the paper printing contrast in the highlight portions of the image. I would like to know about the experiences of others in dealing with this effect. Are you changing your printing technique to overcome it, or are you increasing development time, or are you only using graded paper with negatives developed in PMK?

Regards

Actually, I use vc papers with all my negatives unless there's a specific need to print on fb's. The stain in my hp5+ negatives is on the green/brown side and does not interfere with filtration. Mike
