National Geographic has posted an incredible feature story on the Titanic and some new hi-res imagery of the ship composited from several undersea photos. The images were made in 2010 and 2011 by 3 submarines and each image shown here is made up from about 1500 hi-res images. The link posted above lets you zoom in and pan around. If you don’t want to do that, you can click on the images here to enlarge them (thank you History Blog!).
