People can complain that this is another example of Sherlocking, in which Apple takes a feature pioneered by outside developers and rolls it into the system. And, yes, it is that. Sherlocking has a couple of interesting aspects that aren’t as widely known, though: First, there’s usually room left behind after a “Sherlocking,” and there are several features in Camo that Apple isn’t bothering to replicate with Continuity Camera. Second, the platform owner has powers far beyond those of third-party app developers—and with Continuity Camera, it shows. There’s no app to launch, nothing to configure, no awkward attempt to mount a phone while not touching the wrong button or the wrong place on the screen. When you bring an iPhone (running iOS 16) close to a Mac (running macOS Ventura), the phone’s rear camera can be used as a video source by the Mac. That’s pretty great.<\/p>\n

In essence, the iPhone is automatically detecting when it’s been mounted on or behind your screen and is now ready to be used as a webcam. That’s when the switch of the System Camera occurs. (Apps will need to be updated to recognize the System Camera state, but users should be able to switch between their preferred video sources, regardless.)<\/p>\n

Desk View is an odd one. It’s actually an app called Desk View that displays that faux overhead view, calculated by rotating and de-skewing the output from the ultrawide camera.<\/p>\n<\/blockquote>\n\n

Note that the Continuity Camera feature has been around since macOS 10.14<\/a>. You can use it today in EagleFiler<\/a> to take a photo, scan a document, or draw a sketch with your iPhone (or iPad) and have it automatically imported<\/a> to your Mac. What’s new in Ventura and iOS 16 is that it also works for live video. That’s a great addition, and if you have an old iPhone handy you could even leave it permanently attached to your desktop Mac’s display.<\/p>\n\n

Discover how you can use iPhone as an external camera in any Mac app with Continuity Camera. Whether you’re building video conferencing software or an experience that makes creative use of cameras, we’ll show you how you can enhance your app with automatic camera switching. We’ll also explore how to recognize user-preferred and system-preferred cameras, take you through APIs for high-resolution and high-quality photo capture from iPhone’s video stream, and more.<\/p><\/blockquote>\n\n
