I'm not a fan of HDR as a thing, at all, and I don't know the nitty gritty details any better than any random joe, but I'm pretty damn sure this is a great big stack of pure ignorance.
Ming seems to think that HDR is still back in, I dunno, the 1990s or before. Before anyone had heard of it. The notion of globally mapping tones around is simply wrong.
Yes, a common result is that some lighter tones will map to a darker tone than some darker tones, and vice versa. This is an ancient technique. Good HDR methods are trying to do this (squares A and B are actually the same tone, we've all seen this thing 100x, right?):
In which larger scale tonality alters our perceptions of smaller scale tonality, so create the illusion of greater tonal range.
You know who else used this technique? Ansel Adams and virtually every other darkroom worker in the world.
As soon as you start dodging and burning you're committing Ming's terrible sin of "overlapping tones".
What a mook.
