There are many 'Technical Codes' in media which all manipulate how the audience sees the film to help convey what the directors of films want the audience to be thinking at moments throughout their texts. Camera angles is a main 'Technical Code' which film producers use to show what they are trying to portrait in the way they want it to be shown, to convey certain emotions and feelings about characters and the narrative in the film. A prime example of this would be if a character is shot from a high angle or a low angle, a high angle looking down on the character suggesting little power or importance within the film and a low angle conveying power and status over others in the film.
