The prompt

Medium shot of an older woman with a grey braid at the window of a remote log cabin at night during a winter storm, photoreal horror, locked camera from inside. 0–2s: dim moonlight blue, her face barely visible. 2–4s: a lightning flash floods everything white, showing a dark figure standing far out on the frozen lake. 4–6s: darkness, then a second flash shows the figure much closer, at the end of the wooden dock. 6–8s: darkness again, her breath fogging the glass as she leans closer. Throughout: snow streaking past the window, hard white flashes, deep blue between them, fixed camera, one continuous take.

The light part only, with no subject in it. Put your own reaction in [PERFORMANCE].

Tip

Use two flashes. The first sets the scene, the second shows it has changed. The base light between them sets the genre: cold moonlight for dread, a warm lamp for romance.

Same light, other genre: Lightning, romance version
