I have acquired some Kodak Polycontrast II RC paper, that appears to be circa 1982. What kind of results "should" I expect from paper this old? Or better put, what would happen if I used it normally? And part 2 of same question: Can this paper (if found to be good) be developed in Ilford PQ Universal and have good results? or is Dektol the only way to go? Thank you.
