Apple originally released iOS 15 on September 20th and followed that up with iOS 15.0.1 which exterminated a bug preventing iPhone users wearing a face mask from unlocking their devices using Face ID. With iOS 15.0.1, users wearing an unlocked Apple Watch that they have signed into can unlock their handsets without using their passcodes.
The company is beta testing iOS 15.1 which will return SharePlay to the operating system. SharePlay allows users to share video and audio content with other FaceTime users on the same chat. It also allows users to store a digital copy of their vaccination card in Apple Wallet and adds certain features to the iPhone 13 Pro camera including ProRes. The latter compresses video but does so on a lossless basis.
All you need to know about ProRes is that it improves the quality of the videos you shoot with your iPhone. ProRes is available only for the iPhone 13 Pro and iPhone 13 Pro Max. To enable ProRes, go to Settings > Camera > Formats > and enable the Apple ProRes toggle. Keep in mind that ProRes video capture will use plenty of your storage. Apple reminds users that one minute of 10-bit HDR ProRes uses 1.7 GB of storage for HD and 6 GB for 4K.
ProRes capture supports up to 30fps at 4K and up to 60fps at 1080p for iPhone 13 Pro devices with 256GB of storage and higher. Devices that top out at 128GB of storage are limited to 1080p capture at 30fps.
And with iOS 15.1, users will be able to disable the auto macro mode feature. This will allow users to turn off the feature that automatically enables a macro shot when using the ultra-wide-angle lens to zoom in real tight on a subject.
