I'm finally getting around to posting this. During the 2010 Wetpixel Ultimate Indonesia expedition, we spent 12 days at Misool Eco Resort. Each evening, thunderstorms would rage off in the distance as the sun went down. Don Kehoe and I would sit out on the deck every night with cameras on tripods, taking timelapse frames. It was really incredible.
Cameras have gotten a lot better since then. With a 7D and 1Ds Mark II, it was actually quite difficult to get clean individual frames. I haven't done much cleanup, here—I need to go through and get rid of the stuck pixels.
