John Allen Daviau was an American cinematographer known for his collaborations with Steven Spielberg on E.T. the Extra-Terrestrial (1982), The Color Purple (1985), and Empire of the Sun (1987). He received five Academy Award nominations and two British Academy Film Award nominations, with one win. In addition to his work in film, Daviau served as Cinematographer-in-Residence at UCLA.

The Color Purple is a 1985 American epic coming-of-age period drama film directed by Steven Spielberg and written by Menno Meyjes. It is based on the Pulitzer Prize–winning 1982 novel of the same name by Alice Walker and was Spielberg's eighth film as a director, marking a turning point in his career as it was a departure from the summer blockbusters for which he had become known. It was also the first feature film directed by Spielberg for which John Williams did not compose the music, instead featuring a score by Quincy Jones, who also produced. The film stars Whoopi Goldberg in her breakthrough role, with Danny Glover, Oprah Winfrey, Margaret Avery, and Adolph Caesar.
