O Brother, Where Art Thou? (2000). Joel & Ethan Coen's film was one of the first to be entirely digitally colour-graded. Set in 1930s America, the film has an overall sepia colour tone - the saturated colours of reality are replaced by a hand-tinted effect, giving an idealised version of the dusty Mississippi Delta. Cinematographer Roger Deakins spent many post-production weeks de-saturating the colours to achieve the aesthetic of the Great Depression dust bowl era.
