Hands on: Using the iPhone as a webcam with iOS 16 and macOS Ventura
The iPhone's rear camera system is likely one of the best cameras you own. With macOS Ventura and iOS 16, it can act as your Mac webcam. Here's how it works.

Use your iPhone as a webcam thanks to macOS Ventura Continuity Camera
Apple demoed the new Continuity Camera feature during the WWDC 2022 keynote. A user can attach their iPhone directly to the MacBook lid or an external monitor using a mounting tool and access the rear cameras for use as a system camera.
Since it acts as a system camera, the Continuity Camera automatically appears as an option anywhere cameras can be selected. AppleInsider was able to see the iPhone 13 Pro Max as a camera choice in Skype despite the app not being updated to support it directly.
When using the iPhone as your Mac webcam, the control options appear within Control Center. At the top of the panel, two options appear for controlling the camera and the microphone. Users also get the option of using a different microphone with Continuity Camera, so mix and match as needed.

Comparing iPhone 13 camera modes: Center Stage, Portrait, Studio Light
The camera options include Center Stage, Portrait, Studio Light, and Desk Mode. Sound isolation can be enabled on the microphone too.
Center Stage relies on the ultra wide camera, so it needs plenty of light for noise levels to drop. Deactivate Center Stage and the quality jumps up significantly as the iPhone switches to its main wide camera.

Portrait blurs your background, and Stage Light adds a lighting effect to help brighten your face. All three settings can be used in tandem.
Desk Mode is a bit awkward depending on when you use it. The camera can only see so far down, so it needs plenty of space in front to actually see a "desk." In our testing, Desk Mode focused on our chest at about a 30-degree angle below the camera at three feet away.

Desk mode seems to be closer to 'shirt mode' in the current beta
It seems Desk Mode would work best on a large table attached to a MacBook lid, or it could be a result of the beta. However, even though the ultra wide camera has a really wide field of view, it can't see directly below, despite what the WWDC demo seemed to imply.
Continuity Camera is simple to set up and control. As long as the Mac and iPhone are on the same network, and the iPhone is unlocked, users will be able to take advantage of the feature. Continuity Camera will be available as a feature when macOS Ventura and iOS 16 launch later in 2022.

WWDC should absolutely be every year.
MacOS and iOS should absolutely be updated every year (actually, both are updated several times each year, which is good).
And iPhone as webcam strikes me as an excellent feature. Most webcams suck and the article is right -- the rear camera on the iPhone is likely the best camera most people own.
Remember that WWDC is firstly a Developers Conference to aide and assist 3rd party developers and to help them with the tonnes of changes, features and upcoming changes and features that they will have to account for and deal with. On the surface it might not look like there is a lot of new stuff going on, but there is a lot. Back in the days of real in person conferences there was so much to learn that you didn't have time to take it all in. At least being virtual allows for us to digest it over time. The Keynote is Apple's opportunity for a show and they will use it. It might not have everything that is of interest to a customer, but to a developer these things announced yesterday were huge and full of potential and innovation for 3rd party developers.
We haven't seen a cutoff on which Macs, other than what's required to run the OS.
Or if they’d just enable using external webcams with the iPad then I’d be set.
Didn’t they specifically say during the keynote that the iPhone did not need to be unlocked? Forgive me, I’m just too lazy to go back and find it right now. Or, is this just an early beta limitation that will be fixed before the official release?
It would be cool if: a) using iPhone as webcam is supported on Intel Macs, and b) the various camera options are supported.
But desktop mode was very cool.
Must be for the social media crowd?
And to think people whine about dongles.Sheeesh.
