The Edge Light video effect provides a pleasing fill light to evenly illuminate your face in low-light conditions — like a virtual ring light. And to ensure that you always have access to your content, the effect automatically recedes from the area around your mouse pointer.

From the Video menu that appears in the menu bar when a video call is in progress, choose Edge Light to turn the effect on or off. If using your computer’s built-in camera, the effect appears on your built-in display. If using Continuity Camera (https://support.apple.com/en-us/102546) or other external camera, the effect appears on your primary display.

When Edge Light is turned on, click the arrow next to Edge Light in the menu to reveal additional controls:

• A brightness slider to adjust illumination by changing the width of the effect

• A color temperature slider to make the effect more or less warm. Warmer color temperatures show more yellow and less blue

• A setting to enable Edge Light to turn on automatically when you start a video call and the ambient light is low

Edge Light works best in low-light conditions, such as dim indoor lighting at night. You can combine it with any of the other effects.

Apple actually added two audio modes for apps to take advantage of, Voice Isolation and Wide Spectrum. Voice Isolation is definitely the more useful of the two. Wide Spectrum is not so useful unless your group call has an actual group in one room. That’s because it focuses the audio onto the background noise, minimizing your own voice.

The setting you want for most situations is Voice Isolation. It tunes out background noise when turned on, so you come through clearly and cleanly. That could be removing traffic noise or just the general background hum of a coffeehouse.

To enable Voice Isolation:

• Open an app that supports Mic Modes, such as FaceTime
• Click the FaceTime icon in the menu bar, then click Mic Mode
• Choose Voice Isolation
