Probably if you had a PMK or ABC Pyro neg to compare your Pyrocat-HD negs with you would think them more brown. Here is my own comparison of two pinhole negs taken on the same day developed in PMK and Pyrocat-HD: http://unblinkingeye.com/Articles/Pyrocat2/pyrocat2.html. They can both be said to be greenish, but the PMK neg seems also to be more yellow.(posted 8058 days ago)
