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.

Apple Watch Gets Over-the-Air Software Update Mechanism, But iPhone Still Required For Now
In the first beta of watchOS 6, the Apple Watch gained its own over-the-air software update mechanism under Settings > General > Software Update. As on the iPhone, the mechanism checks for any available watchOS update and, if prompted, downloads the update directly to the Apple Watch.
The mechanism became functional on Monday when Apple seeded the second beta of watchOS 6 to developers.
As noted by Jeremy Horwitz, however, users still must review and accept the watchOS terms and conditions using an iPhone. Hopefully this is a temporary step that Apple removes before watchOS 6 is publicly released in September.
Sure seems like the stage is being set for direct-to-Apple Watch software updates in watchOS 6, though it hasn’t been fully freed quite yet from the need to approve things on the iPhone. pic.twitter.com/pf3wBC3vU5— Jeremy Horwitz (@horwitz) June 17, 2019
Updating an Apple Watch's software previously required using the Apple Watch app on an iPhone for the entire process.
This change is in line with the Apple Watch gradually becoming more independent from the iPhone. In 2017, for example, Apple Watch Series 3 models launched with cellular capabilities for making phone calls and more without an iPhone. And in watchOS 6, the Apple Watch received its own on-wrist App Store.
