[esearing]

Thanks Sandy. Trying to get my head around this by putting this in real life situations; I would assume that both PMK and HD are equivalent for low contrast situations where there are mostly middle tones (ie caucasian portraits or a cloudy day in the woods where shadow contrasts are lacking).

Where these two seem to differ is where the contrast and range of tones at the ends need to be more separated (example slit canyons at mid morning, where sunlight is strong at top of slits, yet still dark at bottom). IT would also appear that HD would not have as much pure black or pure white in a print compared to the PMK print which may or may not be desirable.

PS Thanks for continuing to share your knowledge here and elsewhere.
