  No, it's a property of the film (well, in this case the CCD of the
digital camera, but it works the same way there). Sometimes when you
have extreme overexposure at the border of a frame in a film, the
brightness might even bleed partially to the adjacent frame.

  Without this natural property it would be impossible to photograph
things which are smaller than what the film would normally record, no
matter how bright these things are. However, as we know, if the thing
is bright enough, it will imprint the film no matter how small it is.
