What is a "Qualifier" in color grading?

• A. A tool used to adjust the exposure of the entire image.
• B. A method for automatic grade balancing.
• C. A tool used to isolate a specific color or range of colors for selective correction.
• D. A feature for exporting color profiles.

Answer: (C)

Qualifiers are used to isolate a color range so you can correct only that part of the image. In color grading, you sample a color and refine by hue, saturation, and luminance to create a mask. Then you apply adjustments to that mask, so only pixels in that color range are affected while the rest stays the same. This lets you color correct or stylize elements like skin tones, skies, or foliage without changing the whole frame. It’s not about adjusting exposure across the entire image, nor about automatic grade balancing, nor about exporting color profiles.
