Reading the thread on compensating timers has raised (for me) the question of temperature compensation for PMK. The instruction sheet gives the time reduction for increased temperatures above 68F or 70F, but says nothing about lower temperatures. While summer is coming, my NJ basement darkroom still hovers around 62F (I was just down there printing), raising the obvious question of whether anyone knows PMK compensation factors for temperatures below 68F. I tray develop, and start my processing at 70F, but obviously until summer I have temperature drift downwards. My ZoneVI compensating timer (yup, I'm one of those, having attended one of Fred's courses a very long time ago, and ended up with a very ZoneVI-equipped darkroom!) works well for prints, but I've had some less happy results with PMK in trays. So anyone with curve data (or their experience at specific temperature points) would be great!
