Principal photography had begun by January 21, 2017,[130] at EUE/Screen Gems Studios in the Atlanta metropolitan area,[131][132] under the working title Motherland.[133][134] Filming also took place at Pinewood Studios Atlanta,[135] and in the Sweet Auburn neighborhood in Atlanta, which doubled as Oakland; the High Museum of Art, which served as the fictional Museum of Great Britain in London; and Atlanta City Hall, which served as a United Nations building.[131][136] Cinematographer Rachel Morrison, who was eager to work on Black Panther after working with Coogler on Fruitvale Station,[137] first watched all of the other MCU films to understand the established "language". She wanted to "push" that language and feature more contrast in color. Visual effects supervisor Geoff Baumann provided Morrison with before-and-after shots of scenes from Civil War so she could understand what elements are captured on set and what is created digitally.[138] She filmed in 3.4K ArriRaw with Arri Alexa XT Plus cameras and Panavision Primo lenses,[139] primarily using a two-camera set-up with a third or fourth camera on occasion.
