Jack, I still think there is something for Phase to investigate in the proportional red rise with underexposure. Certainly, all sats rise under those conditions but red rises more than green or blue. I see similar effects with low sun angles of course (different in Los Altos and Melbourne?). Not much to be done as flux dependent balance of the primaries is a fundamental sensor property. However, a red-reduce C1 style might be handy.
I don't have a quantum efficiency chart of the Dalsa chip but I would suspect its red response is extended relative to green/blue and to our eyes. So when all primary fluxes are low or when red light is prevalent (low sun eg), the camera sees more of it than we do visually. Wonder who has the chip response data?
