Ken- Technical perfection and Art are not mutually exclusive. In fact, a degree of both are required. Whether it's 50/50, 75/25, etc., varies.
I've seen technically perfect photos that have left me cold. I've seen great concepts ruined by a lack of competence. I think the danger lies in an over- reliance of one over the other. I think the trick is in knowing which area one is weaker, and working to improve that aspect of the work.
