Which of the following is not a method of white balancing the camera?

• A. Fill the frame with the predominant color on set and select the white balance option in the menu
• B. Use a white balance card and set WB via the menu
• C. Use a gray card and set WB
• D. Adjust white balance in post to correct color

Answer: (A)

White balance is about calibrating the camera's color temperature to make whites look white under the lighting you’re shooting in. The reliable in-camera methods rely on a known neutral reference. Filling the frame with the predominant color on set doesn’t provide that neutral target; the camera would treat that dominant color as if it were neutral, which just propagates that color cast into the image instead of correcting it. In contrast, using a white balance or gray card gives a true neutral reference to set the WB in the menu, and you can also correct color in post if needed. So framing with the dominant color isn’t a valid way to balance the colors in-camera.
