Perhaps a version of RED with this novel filter array just announced from Kodak can be used on the Mysterium?
Kodak are claiming a two stop increase in sensitivity compared to bayer.
Basically they have a fourth pixel that has no filter and this is used for luminance. Trade off is that there are fewer colour samples.
Graeme N, can the RED in camera processing be tweaked to work with different filter array or does the in camera processing go hand in hand with RED RAW?
This idea could also have a use on 3 chip TV camera imagers one chip clear, one green the third with a Red and Blue array.
