Here’s the result of some playtime with the Canon 7D. It’s a 360°x180° panorama of Times Square, played in Flash. Of course there’s much room for improvement – I need to refine my makeshift pano-head and locate the lens’ nodal point* more precisely, but the modest result is fun and immersive. Make sure to click on the Full Screen button at the lower right of the preview below, and once in the real thing, you can click and drag the image in any direction, including up and down… Press Esc to exit Full Screen.
Note: By referring to the nodal point, I seem to be subscribing to a popular panoramic photography misconception; the actual no-parallax point of a lens would be its entrance pupil, not the nodal point.
