Atmosphere is environmental texture in the air and on surfaces: fog, haze, rain, dust, smoke, and wet-down streets that thicken space and catch light. Density, particle scale, and how atmosphere moves with wind or traffic should stay consistent across coverage. Atmosphere is not a substitute for story lighting, but it can motivate shafts, silhouettes, and neon bloom.
AI prompts that specify particle behavior, visibility distance, and whether droplets or dust streak with motion avoid empty “moody fog” defaults. Keep faces readable unless silhouette is the point. This hub covers atmosphere techniques with definitions and AI video prompts. Rain and wet-down streets need consistent droplet scale and ground reflections; dust needs a wind direction. If atmosphere clears for a reveal, mark the timing in the prompt. Copy-ready AI video prompts on each technique page help you specify the same controls a shot list would name.
