Thanks, Jim. The colors in Hawaii are just spectacular so that's not much to add. It's pretty easy to take great photos there! For the trees, that's just the result of the breeze moving the branches during the long exposure. The edges of the trees are blurred more because those thinner branches move more.
Hamish: No, hadn't met him before. I just introduced myself in my e-mail, and then showed up with my wife, 5-year old daughter, and another couple in tow.
