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.

Alleged 2019 iPhone Rear Chassis Appears on Chinese Social Media With Triple-Lens Camera Markings
The above image and mockup (below), shared via Weibo and later tweeted by Ben Geskin, tally with rumors that the next-generation iPhone will feature a rear triple-lens camera system in a triangular configuration.
Last week, an image of a similar chassis piece appeared on Slashleaks, although rumors about triple lenses in an iPhone began way back in May 2018. Well-known Apple analyst Ming-Chi Kuo said in October that he expected the next iPhones to feature triple-lens cameras.
In January, serial mobile leaker Steve Hemmerstoffer (@OnLeaks) released renderings of the supposed iPhone 2019 model, with a similar unusual-looking patch on the rear for three lenses, a flash, and a mic in the triangular arrangement.
The Wall Street Journal has since reported that Apple plans to introduce a triple-lens camera system in at least one of the iPhones coming in 2019. Shortly after that report, Bloomberg seemingly confirmed the rumor, but neither publication mentioned how the lenses would be configured.
A triple-lens rear camera on the next iPhone would allow for a larger field of view, a wider zoom range, improved low light performance, and it would capture more pixels, but the appearance of the lenses and the size of the housing on the leaked images has divided Apple watchers.
