It can also be used to show character growth, foreshadow important information, and create associative meanings between characters that are not explicit in the story. Because the experience of watching a film relies so much on the use of images (although not exclusively, since the film experience always has involved a sound component, even when films were technically silent), most films have an image system at work at some level, whether the filmmaker intends to have one or not. This visual recalling and comparison is inherent in the way audiences extract mean-ing from images to understand a story, constantly making connections between and within shots.
