Regarding the Qualifier on the Color page, does it require adding a Window?

• A. The Qualifier must always use a Window to function.
• B. The Qualifier does not require a window and can be applied to any node.
• C. A window is required only in the Color page.
• D. Windows are only used for power windows, not qualifiers.

Answer: (B)

The thing being tested is how the Qualifier works on the Color page. A Qualifier selects pixels based on their color characteristics (hue, saturation, luminance) so you can isolate a color range and apply adjustments only to those pixels. It operates independently of any spatial mask, meaning it does not require a Window to function. You can apply the Qualifier to a node and affect the whole frame based on the chosen color range. A Window (Power Window) is a separate tool used to constrain the adjustment to a specific region of the image, and you can use it in combination with the Qualifier if you want the color-based adjustment to affect only inside that region. So the best answer is that the Qualifier does not require a window and can be applied to any node.
