Yeah, photography (editing aside) is about having taste and getting lucky. A good photographer can of course raise their odds of getting lucky, but still. There's some technique in there too, but that's really not all that complicated. That said, I think few things match a good photo. There's something about a photo subject being real that I find fascinating. A photo exhibition does not display the imagination of the photographers, but rather the incredible in the real world.

It does, however, display the photographers ability to say "hey, you should see this" and be right about it.
