In my opinion, those photos of the polar bear chasing the man are faked. Look at the right rear paw in the first and second photos. They are malformed blurs. Also, the right front paw or forearm is incomplete in the third photo.


This seems to have originally come from KTVA, but the URL is obsolete: "Polar bear chases man in Kaktovik - KTVA" http://www.ktva.com/ci_8964167


Mykle, you don't seem to have much experience with photography.

The phenomenae you describe are artifacts of motion blur. The shutter is open for a finite amount of time. The faster-moving objects in the photo appear blurred, indistinct, or misshapen. On the first photo, you can see this some of this effect on the man's right leg as well.

Sports photography is done with very large light-gathering lenses so they can use very short shutter speeds to prevent this effect. This was probably a smaller digital camera, or it may have been darker outside than it looks in the photo.
