So, how does 'total light' relate to 'highest image quality? Simply because it tells you, so far as your operation of the camera controls are concerned, how much noise or grain (depending on digital or film) will be in the image. And in the end, all else being equal, noise or grain is the major metric of image quality.

Oh wow, I see I haven't kept up with the times. Last year in the fantasy world where all else is equal resolution was the metric du jour of the technobabblers, a couple of months ago it was dynamic range, now you tell us it is noise. Any chance that you guys will ever consider subject matter, other than test charts and brick walls, and composition as being of some importance?

If little things like resolution, noise, DR, DOF, etc., don't matter to your photography, then you are free to instead participate in discussions that do not involve discussions about these matters. Indeed, DPR has several forums dedicated to the art of photography, as well as challenges, where, I dare say, differences in IQ and/or DOF range between systems seems to play little to no role in the "success" of the photo.

For some photographers, IQ may be the most important aspect of photography. For others, it may play no role at all or simply be an added plus. But it is time well spent to reflect on just how important IQ is to our own photography, given that IQ is, at best, merely a means to achieving a quality image, and, at worst, completely irrelevant to the photo.
