Install iOS 13.3.1 for New iPhone 11 Camera Features
If you own an iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max, and you skipped iOS 13.2, iOS 13.2.2, iOS 13.2.3, and iOS 13.3, you'll probably want to download iOS 13.3.1 in the near future. Here's why.
The iOS 13.2 update included Apple’s Deep Fusion photography system for the iPhone 11 and iPhone 11 Pro series.
If you're unfamiliar, Deep Fusion is an image processing system that utilizes the iPhone 11's A13 Bionic chip and Neural Engine to produce better looking images.
Specifically, your phone will capture multiple images at various exposures, run a pixel-by-pixel analysis, and fuse the highest quality parts of the images together which should result in better textures, more detail, and reduced noise, particularly in low light environments.
If you shoot a ton of photos with your iPhone 11, iPhone 11 Pro, or iPhone 11 Pro Max, and you missed iOS 13.2, iOS 13.2.2, iOS 13.2.3, and iOS 13.3, you'll probably want to install iOS 13.3.1 right now.
