My wife and I spent a week on Lord Howe in August, which was awesome, it's such a beautiful, peaceful place. Of course, the skies are nice and clear too.
Here are a couple of snaps with the camera on a Gorilapod on the grass. Only very minor levels, basically as they came out of the camera.
Canon 7D, Canon 10-22mm at 11mm, f/3.5, 60 seconds at ISO 800
