I've always been a little envious of painters. If you're trying to capture a scene and the clouds aren't quite right, a painter can just make them right. Photographers have to make do with what nature provides — at least at that moment. As one grows as a nature photographer, however, the act of creating an image becomes more like creating a painting. And I'm not talking about the use of Photoshop.
Photography does involve being in the right place at the right time, but that doesn't mean it's always entirely left up to chance.
