L to RGB Exposure Times.
I was shooting some flats earlier tonight and threw in some LRGB while I was at it. I notice that with the same light box setting, L needs 6 Secs exposure to reach 22,000 while Red needed 20 Secs and GB needed 15 Secs.
That's roughly a 4:1 ratio against an LED light box. I'm hoping to shoot off a few subs on a G2V star before I shut up shop to double check the numbers against a white source but does this mean I can knock back my Lum exposures to be a quarter of my colour exposures? Or extend do I extend my colour exposures?
What am I missing here?
