Besides the automatic exposure and white balance, I keep hearing that the photos taken with superior auto mode are "oversampled" but what do they really mean by that? Is it just a downscaled photo? Because every picture dowscaled looks great, so I don't how this is a special thing, so if I tweak the exposure and the while balance I will get manual photos that look like the" superior mode " photos?
I see people complaining that 20 MP is too much for a smartphone with such a "small sensor " that the pictures taken by it, have too much noise .
If I use 8 MP do they have less noise in general or they look like they have less noise only because the picture is smaller?
