Many films conform to the
Classical Hollywood narrative film style, which is a set of guidelines that many filmmakers tend to follow. The story in this style is told chronologically in a cause and effect relationship. The main principle in this film style is
continuity editing, where editing, camera, and sound should be considered "invisible" to the viewers. In other words, attention should not be brought to these elements. While many filmmakers conform to these guidelines, there are other filmmakers that ignore the guidelines and do bring attention to the film techniques. These filmmakers may violate the standard conventions of film in order to create an innovative style or draw attention to particular aspects of film language. The director decides what is and is not on the screen, guiding what the audience looks at and notices. Although the audience may not consciously absorb film style, it still affects the viewer's experience of the film. When viewers watch a film, they may have certain expectations based on previous experiences of film because some techniques are commonly found in film and have become conventional. For example, after a long shot there may commonly be a cut to a closer view. If a character is walking across the stage, the audience expects the camera to pan or follow the character's movement. Viewers expect to interact with and be a part of the film, rather than simply being shown a group of images. These expectations come from experiences with both the real and film worlds; we follow a character in our real world with our eyes, just as a camera pans to follow a character on the screen. The audience expects films to appear like real life, and be shot according to a certain style. Classical Hollywood narrative film styles and the conventions of other genres help to guide the audience in what to expect. Some film makers use styles that challenge these conventions. ==Difference between genre and film style==
