B2

Medium shot of an astronaut in a white suit at a large window of an orbiting station, the planet below in darkness, photoreal sci-fi, slow push-in. 0–2s: only faint blue earthglow on the visor and suit. 2–4s: a thin bright line of sunrise appears along the planet's curved edge. 4–6s: golden sunlight spills over the horizon and floods through the window across the astronaut. 6–8s: the visor blazes with warm reflected light as the astronaut raises a gloved hand against it. Throughout: stars fading, the station frame in silhouette, calm camera movement, one continuous take.
Start with a thin line of light. A sunrise that grows from a sliver reads as dawn; one that pops on reads as a light switch.
