Zoom

This is an example of the zoom camera movement from the movie 'Jaws'. This is normally used to focus into a character in this case it shows the fear on his face. This foreshadows the future events. He sees the people playing in the sea and he looks like he senses that something isn't right. The movement at the end suggests that he's going to get up to do something. The fact that he is getting massaged seems to make him look at ease.
