I understand that the size of the pixels on the sensor basically determines their low light sensitivity performance. The larger the pixel, the more photons which hit it.
So what I'm wondering is, if a 4mp camera is set to a 2mp output, will the sensor's low light performance increase any? I'm wondering if this causes the camera to use 2 of the sensor's pixels instead of just one to create the scaled down image.. or if its just a software trick that discards the extra information.
Thanks,
