DESCRIPTION:
Most of the opening scene in Jaws where Chrissie Watkins is killed by the shark was shot using the 'day for night' technique, adding filters later to darken the image. Here is a lighter version of the scene, closer to how it was originally shot.

Oh, and by the way, the actress was not harmed, she did not break her hip, her rib or her back due to a faulty harness, she's just acting pain and panic. She can be found in interview footage discussing that she had complete control over freeing herself from the harness at any time. So try not to peddle the urban myth that she was brutally harmed whilst filming this scene in the comments section..
