 Butler also created a pontoon camera raft with a waterproof housing that achieved those trademark water level shots that gave a point of view from the shark fin.To stop water drops hitting the lens, Butler used the Panavision Spray Deflector that saw an optical glass spin at high speed to deflect the drops except for the 4th of July beach stampede where the water-lens interface adds to the panic.Butler originally envisioned the look of "Jaws" to start in bright, summer sunshine and then become more ominous as the shark hunt goes on.
