Which action best ensures color accuracy when changing lighting conditions during recording?

• A. White balance using a reference object
• B. Increase ISO until bright enough
• C. Change the shutter speed to 1/60
• D. Lower the aperture to f/16

Answer: (A)

Color accuracy when lighting changes hinges on white balance. Setting white balance with a reference object gives the camera a known neutral target to calibrate its color response to the scene’s current color temperature. By using a white or gray card in the frame, you create a custom white balance so whites stay White and other colors render correctly as light shifts, whether you’re moving from daylight to artificial light or mixing sources. The other options adjust exposure or depth of field rather than color calibration: increasing ISO changes brightness and noise, shutter speed affects motion and exposure, and aperture changes depth of field and exposure but not color balance. So using a reference object for white balance best preserves true colors under changing lighting.
