Tracking Power Windows for Dynamic Adjustments [05:16]
Power Windows can be tracked to follow moving objects within a scene, ensuring consistent grading throughout a shot.
- Case Study: Changing a Coat's Hue [05:21]: A commercial shot featuring a character with a red coat provides an example.

- Gamma in the primary wheels for a subtle, natural dimming.
- Saving as a Preset [09:24]: Once created, a vignette can be saved as a new preset for quick application to other shots, streamlining the grading workflow.
Real-World Example: Relighting a Netflix Broadcast Show Scene [09:48]
The instructor delves into a professional grading scenario from a Netflix documentary, demonstrating how Power Windows are used for subtle but impactful relighting to achieve a cinematic look.
- Initial Scene Assessment [10:42]: The scene, featuring an interview, was deemed too bright for its factual crime subject matter. The director requested a darker background to make the subject stand out.
