At the Worldwide Developers Conference, Apple introduced a new feature called Continuity Camera, which is designed to allow you to use an Apple device as aWebcam for your Mac.
The Continuity Camera is supposed to be mounted on the Mac's display in the right place for all of the features to work correctly. There is no official mounting solution for Continuity Camera at the moment because Apple is working with companies like Belkin to create accessories, but these won't be out until closer to the fall.
If you have a 3D printer and want to try Continuity Camera, Jonathan Wight has created some mount patterns for the MacBook Pro and iMac Pro. Attach one of the mounts to the Mac and you're good to go.
The Continuity Camera works in wired or wireless mode with the Mac, and it is designed to start up automatically when you use theWebcam on the Mac. The rear camera of the iPhone gives it the best possible picture quality.
Portrait Mode blurs the background behind you while Center Stage uses the Ultra Wide camera to keep you centered in the frame. Studio Light dims the background and illuminates the face to replace external lighting, and Desk View uses the Ultra Wide camera to show what's on your desk during a video call.
At the moment, Continuity Camera is available to developers as part of macOS Ventura, with Apple planning to make a public version of the app available in July. For now, the 3D printed options are great for those who have access to a 3D printer.
