The craft aspect I understand and agree with, but as far as the RAW essence of talent, that's just something people are either born with or pick up through life experience (not necessarily a filmmaking experience). In this scenario; raw talent is vividly visualizing that shot/scene before any piece of production is assembled.
Visualization is a very crucial part of the director's chair, so I suppose that's why I went with the Cameron generalization.
Whether you're talented or a hack we ALL need to study Mozart, Scorsese, Jordan, Picasso. My only disagreement was of the notion that one can go from literally talentless to great through reading a book or taking a class. I think we've heard a few users go with the analogy of "short guys playing in the NBA"?
