The film's visual aesthetic is achieved through various techniques, including:
* Color grading: This is a post-production process where colors are digitally adjusted to create a specific look and feel. The film's color grading leans towards muted and faded colors, giving it a vintage quality.
* Cinematography: The film's camerawork and lighting choices contribute to its visual style. For example, the use of natural light and soft focus can create a more wistful and ethereal atmosphere.
* Costume and set design: The film's period setting (the 1930s) is reflected in the characters' clothing and the film's sets.
Therefore, while the film has a distinctly nostalgic feel, it doesn't rely on sepia tone to achieve this. Instead, a combination of creative techniques and visual choices creates the film's unique aesthetic.
