Lighting Passes geben mir Kontrolle über das Licht in der Post. Ich drehe den gleichen Move mit nur Key, nur Fill, nur Rim – der Compositor kann dann alles mischen und anpassen.
A motion-control shot with alternative lighting – same camera movement, different light. Enables maximum flexibility in compositing for light adjustments and effects.
What is a Lighting Pass?
A Lighting Pass (also: Light Pass) is a motion-control shot with alternative lighting – the identical camera movement with different light. In compositing, various Lighting Passes can be mixed to adjust the final lighting or create effects.

The Legacy
History
- Film VFX: Separate element passes
- Digital: More control possible
- Today: Standard in VFX productions
Influence
Lighting Passes have revolutionized lighting control in post-production – what used to have to be final on set can now be adjusted.
Today
| Aspect | Details |
|---|---|
| Frequency | VFX, High-end commercials |
| Trend | Less necessary due to better tools |
| Best Practice | Plan for critical shots |
| Alternative | AI-based relighting |
Modern Development
AI-based relighting makes some Lighting Passes redundant – but for complex situations and maximum quality, they remain indispensable.
From the crafts
Perspectives
Director
Mit Lighting Passes kann ich in der Post noch das Licht verändern. Mehr Drama, weniger Schatten, andere Stimmung – die Flexibilität ist enorm, aber es kostet Zeit am Set.
Producer
Lighting Passes sind Zeit-Investment am Set für Flexibilität in der Post. Bei VFX-lastigen Produktionen lohnt es sich, bei einfachen Setups meist nicht.
