thanks for the information,


I understand then that if I set my 8MP camera, to for example 2MP, the
noise algorithm probably will average 4pixels to create a single pixel. In
this case, I should improve the SNR by reducing the resolution.


Is that correct?

If it is correct, probably I`ll never use 8MP. I'd prefer setting 4MP if I
am not going to have large prints.

But you can get the best of both worlds by doing the noise reduction
averaging, if necessary, afterwards, in an image editor. Note that
you can also reduce noise by averaging the colours into black and
white.
