Selected recipe

Rembrandt Lighting

Rembrandt Lighting is a variant of Portrait Nose-Shadow Patterns. It retains its own complete execution recipe.

Free short AI video prompt

A starter line you can copy. The full timed recipe, still-image and production prompts are on the shot card.

Prompt rule: Adjust key height and offset for the chosen facial shadow pattern, accounting for this face. Hold head orientation and keep gestures clear of the nose; never impose one pattern’s shadow connection on another.

Loop Lighting: A slightly elevated off-axis key produces a short nose shadow that does not join the cheek shadow. Keep the subject readable; motivate camera and light.

Technique guide

When to use
Shapes a character's face with reproducible shadow geometry in a fixed close-up, rather than guessing a light position by style name.
How it works
Fix the face orientation first, and then move the main light instead of the uniform angle of the hard sleeve./Check each selected rule for subnasal symmetry, naso-cheek separation, or connected triangles./Place the gesture outside your chest or face, leaving an unobstructed inspection frame at the end.
Common mistakes
The ring-shaped nose shadow is connected to the cheek shadow, but the name is not changed./The Rembrandt triangle expands into the entire dark side of the cheek.

How to read this page

Loop, Butterfly & Rembrandt Lighting 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.
