In this role the director moves from form into content and concentrates on skillfully and creatively using the tools of the medium to regularly direct the audience's attention to critical aspects of the message. This referred to as an insert shot , a closeup of something significant within the basic scene. The use of an insert shot is simply a way of directing attention to a significant element within the scene. The insert shot forces the audience to look at a significant aspect of the overall scene, while highlighting details that may not be apparent. Good tour guides also help people understand things by adding significant information along the route.
Good directors do the same.
For example, while covering a parade a director might cut away to a shot of a baby sleeping peacefully in a stroller. Or a sequence showing buyers in a busy marketplace in the Philippines might cut away to a shot of a child watching it all. A major role for production tools is to enhance, amplify, or explain the message. Music is a production tool when it enhances the atmosphere, tips us off to danger, or sets the mood for romance. As we will see, lighting can suggest a cheerful atmosphere or a dark, dim and seedy environment.
