This panoramic view of Yankee Stadium on July 4 was shot using GigaPan technology. You can zoom in on any detail – from Alex Rodriguez approaching the plate in the first inning against the Red Sox to the façade of the new Yankee Stadium beyond leftfield. Taken by a robotic camera, the photo was shot over the course of 10 minutes and consists of 124 frames stitched together. Carnegie Mellon developed the GigaPan technology last year in collaboration with NASA.
Here are some other great zoomable panoramics from their website. Everything from nature, to Big Ben, to San Fran, and Augusta National.
