Thanks for contributing to an interesting discussion, everybody. It helps me peek into the world of others, and hopefully it helps us all understand each other better.
It's obvious that photography, as a form of appreciation of craft, art, technology, psychology and so on is like everything else - what we appreciate about it is individual. No matter how much we read, study others, invent and discover on our own, it's ALL filtered through our own brain, which is full of experiences that are unique to each individual.
I have failed, for years now, to understand why having a lens that gives off a crazy weird effect in the corners is actually desirable. I still don't get it. While some of it looks pretty cool in some pictures, more often I find it incredibly distracting and it actually prevents me from appreciating the picture, and most often I just don't care. But maybe I can now at least appreciate how folks reason about it, and that helps me shake some of my prejudice.
Thanks again for contributing. I hope the discussion continues on.
