What really makes big sensors produce more appealing images? *Serious*

in the case of FF vs m4/3's that will be 4 times more light at equal apertures. That translates into better colour depth and hence the appearance of a richer, smoother look.

Ok so help me understand this thing with BOB. You just said exactly what i picture in my head. FF will receive 4x more light than a MFT at equal F stops and equal SS, because at equal F stops the aperture itself isn't really equal. How on earth, with a 4x light advantage, can they get the same SS unless the gain is different? If they are both at ISO 200, both at F2, both at 1/100 SS, and the FF has 2 stops less noise, doesn't it have to be because the gain on the FF was less than the other one? How else would the smaller sensor get those two stops of SS back?

It's a good question and I'd like to know the answer as well

Feel free to read my post about the buckets and surface area.

A cup and a bucket will collect 1" of water in a rain storm at exactly the same rate.

Photodiodes are no different except they dont catch rain, they interact with photons.

They fill at the same rate, yet the bigger ones collect more (quantity not energy) of light.

There is no difference between 'quantity' and 'energy', just that the 'energy' is 'quantised'. In any case  imagine that you have a small pixel and a large pixel, four times the area. Four of the small pixels collect just as much light as one of the big ones.
