Night mode is an automatic setting which takes advantage of the new wide-angle camera that's in the iPhone 11 and 11 Pro models. It's equipped with a larger sensor that is able to let in more light, allowing for brighter photos when the light is low.

Hands-On: iOS 11 Brings Major Updates to the Camera and Photos Apps
In the video below, we've outlined all of the new features you can expect to see in iOS 11 when it's released to the public this fall.
First and foremost, Apple is adopting new photo and video formats (HEVC for video and HEIF for images) that will shrink the size of the photos and videos you take by up to 50 percent. That's going to save valuable storage space on your devices, but the new formats are limited to Apple's most recent iPhones and iPads.
On the iPhone 7 Plus, Portrait Mode now supports optical image stabilization and HDR for better low light performance, and on all iPhones, there are new filters to choose when editing a photo.
When working with Live Photos on a compatible device, there are several new editing options. You can choose a key photo, which lets you select the portion of the Live Photo that looks the best, essentially making it impossible to take a bad photo. Since Live Photos are more or less short videos, it's a lot like taking a still from a video.
Live Photos can now be cropped, much like a video, and there are new Loop, Bounce, and Long Exposure options. Loop causes a Live Photo to loop over and over like a GIF, while Bounce does the same thing, but forwards and then backwards. Long Exposure combines the Live Photo video into a single shot to introduce a unique blur effect.
In the Photos app, there's now dynamic support for viewing Memories videos in portrait or landscape mode, and more kinds of Memories videos are automatically generated thanks to machine learning improvements. New categories include pets, babies, outdoor activities, performances, weddings, birthdays, and sporting events.
The People album, which uses facial recognition to recognize people in images, also now syncs across devices, so it doesn't need to be set up on each individual device.
