Lighting should describe physical sources and transitions, not abstract beauty. A useful lighting prompt tells the model where the light comes from, its color temperature, how shadows behave, what atmosphere catches the light, and whether the light changes during the clip.

Load [ref:color-pipeline-aces] when the user asks for ACES, HDR/SDR, show look, grade, LUT, CDL, product color, or professional color handoff.

Lighting Contract

State: key source, direction, color temperature, atmosphere, shadow behavior, reflective behavior, and any transition.

| Mood or task | Prompt-ready lighting | Why it works | |---|---|---| | Product luxury | narrow warm strip light sweeps across brushed metal, black acrylic reflection remains clean | Material and reflection are controlled. | | Night drama | warm practical lamp from frame left, blue moonlight rim on shoulders, soft hallway shadows | Uses motivated sources. | | Discovery | door crack opens and a thin white beam widens across dust in the air | Light changes with the action. | | Food realism | large soft window light from the right, gentle bounce on the plate, no harsh specular glare | Keeps texture readable. | | Storm atmosphere | cool overcast daylight, intermittent lightning flashes briefly sharpen the silhouette | Weather affects contrast. |

Source Selection

Use practical lamps for interiors, intimacy, and visible motivation. Use window light for naturalism and food or lifestyle scenes. Use rim light when separation matters. Use hard light for noir, harsh sun, or graphic shadows. Use soft light for beauty, skin, product polish, and children or family scenes. Use moving light when the scene needs a visible change.

Color and Atmosphere

Name color temperature only when it matters: warm tungsten, cool moonlight, green fluorescent, sodium streetlight, neutral overcast daylight. Add atmosphere sparingly: mist, dust, rain streaks, smoke, or condensation should interact with the light and the subject, not merely decorate the frame.

Failure Fixes

If an output looks flat, add a motivated key source, rim separation, and one material-specific highlight. If it looks over-processed, remove broad style claims and specify softer contrast. If flicker or lighting jumps appear, make the light source stable and remove competing transitions.

Output Contract

Return a compact lighting block, a transition note if needed, and one prompt-ready integrated sentence.
