True or false? A LUT can hold complex information, such as Power Windows.

• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (B)

LUTs define a color transformation as a table that maps input RGB values to output RGB values. They are designed for applying a consistent, global look or correction across the entire image, not for storing per-image region data or dynamic controls. Power Windows, on the other hand, are region-based masks with tracking and keyframed adjustments that live in the node/grading setup and are applied selectively to parts of the frame. That kind of localized, often animated information isn’t stored inside a LUT. So the idea that a LUT can hold complex information like Power Windows isn’t accurate. In practice you’d use a LUT for the overall grade and apply Power Windows separately on top for regional tweaks.
