We arrived back home about 5 AM from Tokyo and Portland and I took my camera and tripod out for a walk before sunrise. As the sky began to show a little color I noticed the billowing clouds in the sky behind the Marina Bay Sands casino and tried a few frames. Below is the one I selected to post. (Note this image needed to be run through Imagenomic Noiseware Professional to remove a rather intrusive amount of noise, something I don't usually need to do with these low light images).
