Re: EXR Confusion not fully resolved

Sorry to correct you, but L and M size collect the same amount of photons as sensor size is the same. What happens in M size (DR 100) is that noise is calculated out by averaging two sensels into one. It's the same as looking at the "Print" vs. "Screen" resolution graphs at DxOmark. The benefit of the EXR sensor versus downsizing in post is that the averaging on the EXR sensor always happens between sensels of same filter-color and close proximity.
