Thanks. I use it primarily because it has a 10-year shelf life and one-shot application. I don't prefer developers that need time compensation after X-number of rolls or degrade with time once mixed. You only get one shot at the negative so I prefer to reduce the variables as much as possible with the developer.
I've used it for a long time so I stick with it because I know it. The pyro stain makes for a compensating developer. For normal contrast scenes it is just a run-of-the-mill developer. But for high contrast and highlight compression development methods, it makes more sense. Also, in the wet print days, the pyro stain had a feature. You could burn/dodge highlights and shadows separately by using filters on the enlarger with multigrade paper.
The shot below was a test shot of "Minus-X" development with PMK. It is a radical highlight compression method. This is 400 film shot at f11 and 4 seconds due to the low light inside. Take 400 film outside in the bright sun and shoot it at that setting and you'll blow highlights for sure. But yet in this scene things in the bright sun was captured. Behind the girl's back measured EV3 and the concrete outside the window measured EV15.
Many digital cameras claim 12 or 14EV for sensor dynamic range. But I really don't think that is what you actually get in the end photo. If I shoot my digital with it's reported 12.4EV DR at ISO 400, f11 and 1/2 second exposure in the Sun, highlights will be blown like crazy. So where is the 12EV DR, I wonder.
There is no need to sell you on this developer. Just pick one and stick to it for a while. They all work fine.
