The Qualifier is a tool used for what purpose?

• A. a tool used to isolate a specific color or a range of colors in a video clip
• B. a tool to sharpen edges
• C. a tool to adjust white balance
• D. a tool to blur noise

Answer: (A)

Isolating a color range so you can apply selective adjustments is what the Qualifier is designed to do. In the Color page, you sample a target color with the eyedropper and then fine‑tune which pixels are included by adjusting Hue, Saturation, and Luminance thresholds. Once you’ve defined that mask, any grading you apply—whether it’s changing color, saturation, or brightness—affects only the selected colors, and you can feather the edges for a smooth blend. This is especially handy for tweaking skin tones without altering the rest of the image or changing just the sky or greens in a scene. It’s not used for sharpening, white balance, or noise reduction, which are handled by other tools.
