Apple recently announced the developer beta for iOS 14.3 which brings with it Apple’s new ProRAW photo feature. iPhones have actually had DNG RAW capabilities since iOS 10, but it’s never offered this capability in the built-in camera app before. You’ve always had to go for third party solutions, like Camera+ or Lightroom.
But now, Apple is implementing it in their own camera app and they’re calling it “ProRAW”. And according to PetaPixel, the cameras within the iPhone 12 Pro and iPhone 12 Pro Max will allow it to capture 12-bit DNG files with up to 14-stops of dynamic range. Other than the capabilities of the actual camera module itself, though, I’m not sure what it offers that iPhone users couldn’t do already.
