Noise vs resolution — part 1
It’s a truism that sensors with larger photosites have less noise. But you can reduce noise by combining information from small photosites into fewer pixels than with a standard Bayer conversion. In my mind, this is ideally performed before demosaicing, but raw converters don’t, in my experience, allow to to choose the resolution rendered by… [Read More]
