Just popping a question probably I have already answered myself. As we all know that having higher pixel count and shooting at higher ISO is asking for noise. Anyway, taking an example below,
14 MP + @1600 ISO = Noisy Pic
Lowering MP to say 8 MP + @1600 ISO = Lesser Noise Pic? Due to lower resolution the sensor is capturing.
Then how about shooting @ 14MP, resizing image to size of a 8MP. Does it makes a difference?
