Continuity Camera is a macOS feature that allows you to use your iPhone as a webcam on your Mac. With Continuity Camera, you can take advantage of the powerful iPhone camera and additional video effects, such as Center Stage, Portrait mode, Studio Light, and Desk View. You can connect your iPhone to your Mac wirelessly or with a USB cable, and choose your iPhone as the camera or microphone in apps that support it, such as FaceTime or Photo Booth1. The other options, Focus, Stage Manager, and Quick Look, are not macOS features that allow you to use your iPhone as a webcam. Focus is a feature that helps you reduce distractions and stay focused on what matters to you2. Stage Manager is a third-party app that lets you control your livestream from your iPhone3.
