Lot's of false arguments have been raised here to discount the worrying concept of talent; worrying, because it implies the existence of something that can't be bought or attained or derived from repetition. In other words, it's not egalitarian and must therefore be denied.
Actually, I think the worrying concept here is that talent has to be earned. You can't excuse yourself by saying "I just wasn't born lucky." I think that people who believe in in-born talent should read the books we've been talking about (if they're really interested in the question of talent. If not, then don't worry about it.) These are not one-note books -- talent is a very complex thing, as is learning, and these books make that point. For example, the guy here who talks about his brother who can coax a tune quickly from almost any instrument. It's possible that his brother has perfect pitch, which makes that much easier. But perfect pitch is learned. Most Chinese and Vietnamese have it, because their languages are tonal, and they're taught pitch from the time they're infants. Some westerners also have it, but it's learned. And, I suspect this brother can mostly play certain kinds of instruments -- perhaps guitars and pianos, where the note relationships are easily learned. I bet he can't pick up a trumpet or an oboe (without previous training) and get good notes from it...
When you're discussing those things, you have to pay very close attention to what you call "talent." For example, Anthony Shadid, the New York Times reporter who just died in Syria (of an asthma attack) won two Pulitzers, and was one of the most highly regarded reporters in the world. But, he wasn't a great writer, nor, in terms of actual question-and-answer stuff, did he seem to be a great reporter. That is, he didn't ask questions that most other good reporters wouldn't ask in the same circumstances. What made him a great talent was actually his *will* to do things -- to go places that others would not (because of fear), to report on dangerous events, and to do it over and over and over. His talent was a will to witness, more than anything else. That's what makes most great war photographers -- the will to witness, and the bravery to stay with it. The camera work is actually relatively trivial. So, when you're talking about talent, you always have to ask, "Exactly what talent are we talking about?"
You also have to understand (about this argument) that "learning" is not mechanical. We're not talking about 10,000 hours learning to handle a camera -- we're talking about serious, in-depth investigation of ideas and themes that explore the whole range of photographic possibilities, or a few possibilities to great depth. You actually *can* think about such things, if you're inclined to. It's not all running out and shooting a lot of pictures. That's just taking snapshots, and like flicking a light switch, doesn't take a lot of ability. It's the thinking about new possibilities that's hard, and that develops talent.
