Seeing
Anyone can become a photographer by buying a camera, just a as anyone can become a writer by buying a pencil, but to be good requires more than mere technical skill. You can tell immediately if someone is good. They're gifted with a sense of style a sense of composition and a sense of sense. It's instinctive. All the technique in the world doesn't compensate for the inability to notice things. in fact it just gets in the way. The most important thing is to be able to "see".
