There are many images of Cassini with Saturn in the background on the internet. How are these photos taken? Is the video of Cassini disintegrating in Saturn's Atmosphere real or made using graphics?
Any picture of Cassini in space is an artist's conception, probably a computer rendering, although the Saturn backdrop may come from real Cassini photographs.
I had thought it possible that the Huygens probe carried by Cassini to Titan might have taken one or more pictures of Cassini as it departed, but it's not possible, as the camera was enclosed under the probe's heat shield until it was well into its descent.
