Which color grading scope is used to assess brightness across the image?

• A. Waveform
• B. Histogram
• C. Vectorscope
• D. Parade scope

Answer: (D)

When you want to judge how bright the image is overall, you need a scope that shows luminance information across all color channels in one view. The parade scope presents the red, green, and blue channel data side by side, so you can see how bright each part of the frame is and how the channels contribute to that brightness. This makes it easy to spot overexposure, clipping in any channel, and imbalances that affect perceived brightness across the image. In contrast, a waveform focuses on luminance per pixel, a histogram shows the distribution of brightness values, and a vectorscope analyzes hue and saturation rather than brightness.
