Reverse Track Shot

In this scene of "Jaws" we see how the character Brody has realised that someone has been attacked by a shark. By using a reverse track shot the director shows that the character has caught on to what is happening in front of him. It also gives the effect that everything is flying past him slowly but his mind is racing about the event in front of him and what he should do. It also helps give off the look of fear on the characters face.
