Camera techniques like extreme close-ups and tracking shots were used to represent differences in class between characters. An extreme close-up of bin men eating emphasized their lower-class habits, while a tracking shot showed Lady Macbeth's refined manners during a high-class dinner inspection. Dialogue also revealed class distinctions - the bin men spoke with strong northern accents while Lady Macbeth used a "posh" accent. Macbeth's loud voice in the kitchen and the respect he commanded showed his high status as a skilled chef. Lady Macbeth's formal body language further signified her image-conscious, high-class character.
