Dizzy yet?? Use your cursor to control the image and view a full 360°. These panoramas of Grand Central Terminal in New York City were photographed with the Canon 7D and Sigma's 4.5mm F2.8 EX DC HSM Circular Fisheye. (Grand Central Station is actually below the Terminal where the subways are.) More about this spectacular Sigma lens and creating 360° panoramas next week.
