A starter line you can copy. The full timed recipe, still-image and production prompts are on the shot card.
Prompt rule: Keep the near-axis source weak enough not to replace cheek modeling. Catchlights must be corneal reflections that occlude during a blink and move plausibly with gaze.
Eye Light: A weak near-axis source produces small reflected catchlights without substantially replacing the face's key and shadows. Keep the subject readable; motivate camera and light.
Technique guide
- When to use
- Maintain the direction of the eyes and the sense of life in the darkened close-up, and do not flatten the entire face.
- How it works
- First, form a lateral face shape, and then fine-tune the height and intensity of the small light next to the mirror axis./Schedule a blink and a small eye movement to check the reflex occlusion and following relationship.
- Common mistakes
- Pupils are white or irises are glowing./Added light to completely flatten the dark side.
How to read this page
Eye Light (Catchlight) is one technique in Lighting. The definition states the single mechanism the frame has to show. The technique guide covers when to use it, the steps, the usual mistakes, how it differs from the neighbors, and what a successful take looks like.
The clip above is one reading, made with a third-party video model. Another model, or the same model on another day, can land on a different frame. It is an example, not a promise that a prompt will match it.
The free short prompt is a starter sentence. The shot card is the timed recipe: scene, start and end frames, action, light, and color. Three sample cards are free on the site. The rest are part of GrokCine Pro. A second name for the same shot keeps its own URL and points back at this definition.
When you write a prompt, keep the one mechanism in the definition, then name the subject, the motion, and why the light is there. Do not stack a neighboring technique into the same sentence. If the name or the example is wrong, send this page's URL from the contact page.
