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 Takes Early Step Towards iPhones With 'Above 12-Megapixel' Rear Cameras
The report, citing "market rumors," claims Largan is the only supplier that can meet Apple's minimum yield rate. The new factory is reportedly designed to accommodate monthly production of 600 million lens modules.
Largan will allegedly start production in October 2017, suggesting the camera lens modules could be destined for future iPhone models released in 2018 or later, rather than the so-called iPhone 8 this fall.
It is widely rumored that the iPhone 8 will have a vertically-aligned dual-lens rear camera, with optical image stabilization for both the wide-angle and telephoto lenses, but no credible rumors have surfaced about its quality.
Apple improves its iPhone cameras each year, so an increased megapixel count of some kind is certainly still possible this year.
Apple's latest iPhone and iPad models, including the iPhone 7, iPhone 7 Plus, 10.5-inch iPad Pro, and 12.9-inch iPad Pro, are all equipped with 12-megapixel rear-facing cameras and 7-megapixel front-facing cameras.
Keep in mind that megapixels don't always matter, as even a TV or monitor with 4K Ultra HD resolution of 3,840×2,160 pixels only has roughly 8.3 megapixels, which isn't enough to display a 12-megapixel photo at full resolution.
Nevertheless, if this rumor is accurate, then perhaps we'll see an iPhone with a 16- or 18-megapixel rear camera or higher in the future.
