The document discusses how the film Kes, directed by Ken Loach, uses cinematography techniques like set decoration, lighting, and color design to represent the poverty experienced by the characters. Specifically, the cramped and poorly decorated setting depicts the lack of space and comfort in their lives. The low-key lighting and desaturated color palette create a gloomy atmosphere that evokes sympathy by showing the characters' depression and making viewers uncomfortable. These technical elements address the issues of lack of space and privacy in ways that highlight humans' basic needs.
