There's a photo here of the inauguration of President Obama. On the face of it, it's an incredible camera that took the shot because you can zoom right in on individual people. The zoom is at the top left and you can move the image by clicking on it and moving the mouse. Sometimes you have to click again to make the mouse let go, and it might take a moment to update now and then. It's a big image.
Look at the bottom of the press tower, the big white thing opposite the President. There's a policeman right next to a doppelganger of himself. Follow along the railings, and you'll see a pair of disembodied legs. Further along is another blurry manifestation.
Unfortunately for those who believe such cameras exist, and for those of us on the lookout for spontaneous paranormal imagery, the real story is more mundane. It's a composite image of many small photos. It's extremely well done, but a few people (the policeman, the legs, the blurry image) moved between shots and spoiled the matching of the edges of the photos. No fancy spy camera here, and no ghosts.
It's still worth a look. If you were in that crowd you might be able to spot yourself.
