A friend sent me a link to this beautiful video, and here is the video description:
A time lapse video made by setting a camera to take photos at six second intervals during a trip outbound on the Houston Ship Channel. I used Quicktime to assemble over 2000 individual photos into a 3 minute movie representing an actual time of over 3 1/2 hours. The ship was only moving at 5-6 knots for the first half of the trip and up to 10 knots in the open areas away from the docks. The journey begins just below the Port of Houston turning basin at the end of the channel and continues down to Morgan's Point at the head of Galveston Bay. We still had 32 miles to go to get out to the pilot station in the Gulf of Mexico at that point. The ship is a Panamax tanker 600 feet long by 106 feet wide.
My photos of the Houston Ship Channel (and other subjects) can be found at flickr.
