Key lightแสงที่เล่าเรื่องแทนคำพูด

Key light: in an abandoned train station, one adult woman stands beside a rusted ticket booth as a single hard light source, a shaft of late afternoon sun through a broken skylight, strikes the left side of her face at a 45 degree angle, carving deep shadow across her right cheek and jaw. The camera stays locked on a static tripod, 50mm lens, as dust drifts through the beam. No fill light lifts the shadow side, no other source competes, the rest of the station remains in near darkness. She turns her head slowly toward the light, shadow sweeping across her features in real time. No text.
