It was straightforward to snicker yesterday when Apple revealed that you’ll soon be able to stick an iPhone on the back of your Mac to get a greater webcam. Some joked that Apple design legend Jony Ive was off crying somewhere. Others puzzled whether or not this was actually the most effective Apple may give you after years of grainy MacBook photographs and the way the Apple Studio Display’s camera fell short.

However right this moment, Apple software program engineer Karen Xing spent some time explaining how the brand new Continuity Digicam characteristic for macOS Ventura will truly work at WWDC 2022 — and it sounds critically spectacular. It may make your iPhone a full-fledged digital camera for Mac, one which does most every thing you’d count on and extra.

In the event you don’t need to watch a 20-minute presentation, right here’s the TL;DR:

macOS will detect your iPhone as a digital camera and microphone, interval, so each digital camera app ought to work. Whereas Apple solely confirmed off FaceTime and talked about Zoom, Groups, and Webex throughout the large WWDC 2022 keynote, builders shouldn’t must do something to their apps for them to work.

It’s… a digital camera! No particular APIs required.

You get Portrait Mode, “Studio Gentle,” and Heart Stage choices whatever the app, too. They’re in a Management Heart dropdown menu, alongside your iPhone’s battery.

You’ll be able to flip your iPhone to any orientation, and it’ll nonetheless work. You get a zoomed-in impact in case your iPhone’s in portrait orientation. Right here’s a fast and soiled picture slider of the distinction:

Tough concept of portrait vs. panorama orientation.

FaceTime isn’t the one app that’ll “magically” change to your iPhone while you plop it down. Xing demoed that with Zoom, and Apple’s offering up an computerized digital camera choice API that different apps can use, too. macOS Ventura will mechanically change to your iPhone if it’s mounted on a stand and both plugged in through USB or detected as “close by” utilizing Bluetooth and Wi-Fi.

Apple recommends giving customers a toggle to show off computerized digital camera choice, too.

It really works wired — not simply wi-fi. USB cables are fantastic for those who’re nervous about interference or your iPhone staying charged.

Apps can let your Mac seize images and video out of your iPhone, too. Plus, it might probably optionally cross alongside face detection and physique detection “metadata,” which sounds a bit intriguing and a bit creepy on the similar time. Captures max out at 1920 x 1440 and 60fps.

There’s an API for Apple’s nifty Desk View mode, too. Apple found out a option to bend and crop photographs from the iPhone’s super-ultrawide lens to allow you to showcase issues on the floor of your desk with out shifting your telephone. That’s out there for app devs, too, and Xing confirmed it off as a option to current in Zoom:

You’ll be able to choose Desk View in Zoom similar to some other presentation instrument.

App builders may also seize 30fps, 1920 x 1440-res video from Desk View.

(You’ll be able to see a greater demo of Desk View at 1:40 in this video.)

Sadly, none of this works with these {old} iPhones you’ve obtained sitting in a drawer. Continuity Digicam requires iOS 16 along with macOS 13, Xing revealed — and sadly, the iPhone 6S, 7, and first-gen iPhone SE and earlier won’t be getting the iOS 16 software update. That’s a disgrace as a result of it feels prefer it may very well be a good way to utilize an older telephone that doesn’t have resale worth. Nonetheless, there are other ways to turn an old spare phone into a webcam.
