As far as this method being subjective, isn't all our work? When we take readings and expose for our goal, aren't we subjecting the image our interpretation? Not to mention focusing based on our eyesight. I would think that using this method, you could replicate the detail at your desired level.
wait...this is based on someone's subjective opinion of "details", right? is that right? it's based on someone's eyeball perception? with no previous calibration to the particular person. Just so this is nice and sparkling clear--is this how it works?--the perception of the individual? Or is there some detail here that's not being seen?
