So one might reasonably conclude for individual pixels:

More light less noise.
Larger pixel more light.
Larger pixel less noise.

The catch is in comparing noise at the image level. Right?

Which brings in:



Isn't this the same as saying, normalizing for pixel size? which is also the same as normalizing resolution?

Cheers,

This has helped clarify things Michael, except for one slight modification to your thesis:

More light same amount of noise
Larger pixel more light.
Larger pixel same amount of noise.
Larger pixel higher signal to noise ratio

all of this at the individual pixel level, like you said.
