The Wizard of Oz (1939 film)

All of the Oz sequences were filmed in three-strip Technicolor. The opening and closing credits, as well as the Kansas sequences, were filmed in black and white and colored in a sepia-tone process. Sepia-toned film was also used in the scene where Aunt Em appears in the Wicked Witch's crystal ball.
