You evidently don't understand it. That's why I explained it for you. It has nothing to do with personal bias.

A couple of useful tutorials, 1, 2.


No, I understand it perfectly, it has everything to do with personal bias. The bias has nothing to do with objective decisions. From that tutorial, "opportunity of biasing the exposure toward the brighter tones" - like I said, this is all about attempting to get as far as possible with biasing exposure "to the right". Obviously, people usually want to do that without clipping things too much, and it's always a matter of trying to get a good balance, but when people say that rather than trying to get a good balance in general, they're "exposing to the right" it means to me that they're obsessed with trying to maximize the exposure and they risk clipping or degrading the quality of highlights more than someone who simply practices sensible exposure based on the conditions and requirements of the shot.

By the way, obviously, in many situations, if you're totally obsessed with "exposing to the right", you're never gonna get the shot, because the shutter speed required for it is way too low. The writer of that tutorial (#1) seems completely oblivious to the fact that even in rather bright surroundings, in many cases "ETTR" would mean unacceptably low shutter speed. It's all a matter of balance and it is in fact all about personal biases. An auto "ETTR bias mode" may be a nice thing to add to cameras, but it's absolutely not a proper replacement for the normal auto exposure modes.

For me, maybe exclusively and personally, this.  We've become so obsessed with image noise that is has become almost a religion to seek the lowest you can get, even if that risks damage to other data quality at time of capture.

Just read the forums: 'shot noise', 'photon noise', ISO invariance, it's become a veritable insatiable quest for some theoretically 'best' exposure.  Because an extra 1/2-stop of noise will destroy the value of your photo's visual statement, don't you know.
