Auto White Balance is used to respond to mixed lighting by:

• A. It sharpens the image to reveal more detail
• B. The camera automatically sets white balance to match the true color of the subject.
• C. It adjusts exposure automatically
• D. It changes the ISO automatically

Answer: (B)

Auto White Balance tackles color temperature and color casts. When lighting is mixed, different light sources (like sun and indoor bulbs) can tint a scene in different colors. White balance adjusts so that whites appear white and overall colors look natural. Auto White Balance does this automatically, estimating the scene’s lighting and setting the camera’s color balance to match what the image should look like under neutral lighting. That’s why this option best describes AWB’s function. Sharpening boosts detail, exposure changes brightness, and ISO alters sensor sensitivity—none of those fix the color cast that AWB targets.
