Stern shot "Changeling" in anamorphic format on 35mm film using Kodak Vision 500T 5279 film stock. The film was shot on Panavision cameras and C-Series lenses. Due to the large number of sets, the lighting rigs were more extensive than on other Eastwood productions. The crew made several ceilings from bleached muslin tiles. Stern lit the tiles from above to produce a soft, warm light that was intended to evoke the period through tones close to antique and sepia. The crew segregated the tiles using fire safety fabric Duvatyn to prevent light spilling onto neighboring clusters. The key light was generally softer to match the warm tones given off by the toplights. Stern used stronger skypans—more intense than is commonly used for key lighting—to reduce contrasts when applying daytime rain effects, as a single light source tended to produce harder shadows.
