E4

Medium shot of a weathered woman rancher in a wide-brimmed hat stepping from the bright doorway of a barn into lantern light, photoreal western, locked camera from inside the barn. 0–2s: she is a black silhouette against blazing white daylight in the doorway. 2–4s: she steps forward into the barn. 4–6s: warm lantern light catches her face, the details of her coat and features filling in. 6–8s: her face is fully lit, the bright doorway behind her, as she stops and looks ahead. Throughout: hay dust floating in the light, wooden beams, fixed camera, one continuous take.
Name both lights: the bright opening behind and the key in front. The reveal is the subject walking from one into the other.
