I don't see it so much as snobbery as apathy, boredom and perhaps some dismay. Photography is almost 200 years old. There really isn't anything all that new. It's been done before, sometimes on purpose, sometimes by accident. A lot of those accidents never really saw the light of day because they were not popular. Tastes change.
20 years ago you wouldn't see barbells in peoples eyes, ears, noses, tongues, nipples, belly button, and places I won't name. Now they are common place. Does that mean I want to see and marvel over all those barbells and other bits of body jewelry or find it fascinating or that I have too?
HDR is just another form of art. There are some that I have seen that I do like some I don't. My only complaint with it or any form of art that seems to capture the fascination of so many is if you like it great. But it doesn't mean that I have to as well.
I guess that means I don't have to worry about my wife getting me a gift certificate for nipple piercing for Christmas.
