Re: SNR vs exposure

Sure, but noise, as a problem that spoils a print or the image on the screen, is not a highlight problem, it is a shadow problem, and even where there is a lot of light in a scene overall, the shadows are still dark. Black is black (I want my detail back) and grey is grey (I want it here today), what can I do (except turn up the ISOO)?

Plus, we usually take our photographs with a hand-held camera and often have moving subjects, so we must use short exposures and cannot, as a scientific or astronomical photographer can, wait for the wells to fill and therefore use low gain so the black sky stays black, not speckled.
