You can now download iOS 13.2 beta for iPhone and iPadOS 13.2 beta for iPad. It packs Deep Fusion for iPhone 11 users.

Apple showed off a nice little feature in its iPhone 11 keynote where the newly announced smartphone would snap several photos, stitch them together and you’ll be left with an image that’s extremely dense in terms of quality. That feature is called Deep Fusion and it is now available for iPhone 11 and iPhone 11 Pro users as long as you are a registered developer with Apple. Yes, that means you have to download iOS 13.2 beta straight from Apple in order to test this feature out. But you already figured that out, didn’t you?
