Prompt rule: Raise shadow information without reversing or equalizing the main modeling direction. Use a broad contribution that does not create a competing sharp shadow; light ratios are setup references, not pixel ratios.
Fill Light: Secondary illumination raises shadow visibility while preserving the dominant direction established by the key. Keep the subject readable; motivate camera and light.
Technique guide
- When to use
- Let dark clothing, the dark side of the face, or the shady side of the object retain the necessary information.
- How it works
- Check the main light and fill light contribution separately to ensure that the main direction is established first./Gradually add a wide reflective fill to verify that the stitching is read inside the flipped neckline.
- Common mistakes
- The same light on both sides causes the volume to disappear./Prove the incident light ratio directly with the brightness of the display pixels.
How to read this page
Fill Light 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.
