Apple has just released iOS 13.2. If you own a new iPhone 11 or iPhone 11 Pro, you'll want to download this update as soon as possible as it includes Apple's new Deep Fusion photography feature. In short, the feature is Apple's response to recent advancements made by Google in computational photography. In the words of Phil Schiller, the feature uses "computational photography mad science" to process photos in a way that makes them look more natural, with less noise and better detail. The "mad science," as it were, is that the feature takes advantage of machine learning and image stacking to render each pixel of a photo optimally. You'll likely see the benefits of Apple's new approach most in less than ideal lighting conditions, but it should help to improve all your photos.
