When using an iPhone 11 or newer on iOS 16 with a Mac on Monterey OS as a webcam, the phones wide angle lens has two jobs: it can be used to display the Centre Stage video effect and Desk View. The latter cleverly gives a view of the desk space between the user and the keyboard.
This is via the Desk View app, one of several apps in the CoreServices section of the Mac's System Library.
Since the Desk View is done via an app, it can be displayed in a Zoom meeting via Screen Sharing.
One would reasonably assume, that because the wide angle lens was in use with Desk View, that it couldn't be used simultaneously with the Centre Stage video effect.
But that's not so. Both Centre Stage and Desk view can use the wide angle camera lens simultaneously.
That is very clever.
