Very nice and fine grained. PPD developers have been used for over 100 years but are often slow in development.

A note about one shot developers with no antioxidant! Films and papers are designed for the presence of antioxidants and thus the developer is too "HOT" if the Sulfite and HAS are removed. You can get severe color contamination. In fact, in one of my experiments, my boss called the colors cyan, grape and pumpkin. Pretty bad.
