Codes and conventions are tools like music, script, costumes, and camera angles that filmmakers use to help audiences understand characters and their roles in the story. How these tools are used, or conventions, can influence whether audiences like or dislike characters and comprehend their importance. For example, if a character is shown entering a building at night with threatening music, audiences may view them as a thief, but if they are in bright light with pleasant music, they may seem like a regular employee working late. Audio, symbolic, and technical codes also provide clues through dialogue, imagery, camera work, and more.
