The MacBook Pro Stage Light Effect can make video calls look clearer by improving how your face is lit and reducing the impact of a dim or bright background. On supported Mac models and macOS versions, Apple offers Studio Light, which darkens the background while brightening your face during video calls. To use it, start a compatible video call, open the Video menu in the macOS menu bar, and select Studio Light. You can also adjust its intensity to achieve a more natural look.
