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 Seeds First Beta of iOS 11.1 to Developers
Registered developers can download the iOS 11 beta from Apple's Developer Center or over-the-air once the proper configuration profile has been installed from the Developer Center.
Several iOS 11 features did not make it into the first public release and these could potentially be included in the iOS 11.1 beta.
Apple has said both peer-to-peer Apple Pay payments and iCloud support for iMessages will be introduced in later iOS 11 updates, and new emoji characters are expected at some point.
iOS 11 marks a major update to the operating system, with systemwide design tweaks, a new Lock screen experience, a revamped Control Center, and an entirely new interface for the iPad that includes a Dock, Drag and Drop support, and a redesigned App Switcher for better than ever multitasking.
