When it comes to wildlife and birds, I believe we must separate between amateurs and pros. I am an amateur and my photography is partly an excuse to be out in nature, partly to succeed in my hunt for a specific animal/bird and partly to try to be as good as some of the pros. I take great pride in an image from time to time. I believe Edward (eml58) is in a similar position, given that he is not trying to sell his images, he just shoots more spectacular ones than the rest of us.
It's good to hear so many people feel there are plenty of opportunities left to create something new and unique, even if it doesn't happen very often.
I admit that my post was bing written a bit as advocatus diaboli
, but at least for fireflies that I shoot 1-2 times a year I still find it difficult. You get some shots that are really good, focus spot-on, terrific framing, everything's peachy - and then back home when researching for the name of the animal you find shots with double the resolution and double the lens' (price) right there on wikipedia :-p
For everything else that's a bit more mammal-like (or can appear that way) it's easier to picture emotions, stories and relationships that go beyond the simply visual/tech aspect of the shot (like in: "smooth bokeh").
