Description

Processing this time benefited from reading the instruction on PI HDR Combination. Somewhere they emphasize that the difference in exposure between the brightest and dimmest HDR masters should be at least 10X.

Subsequently color from the RGB was highly saturated before adding in the high L signal.

The LUT is the Indian Summer again which separates B & R. It does include some "teal" and I think that is probably there but could remove it.
