Sandy,

I have now developed for SBRs of 11 and 13 (5m30s and 3m respectively). I still cannot believe how versatile PYROCAT HD is (and quite economical at 1:1:100 for these extreme SBRs). The negs look like they have been developed normally. In fact, I feel as if these scenes are not as extreme as I had thought when I took them. Your suggested times are spot on and I do not hesitate to recommend them using Efke PL100 8x10. A wonderful and easy combination! My next project is to try Classic 400 once I take a few more on PL100: Thank you very much once again.
