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.

iPhone 8 Camera Allows Users to Customize 3D Animated Emoji Using Facial Expressions
Based on information in the iOS 11 GM firmware, the new "Animoji", as they're called, appear to be a feature exclusive to Apple's so-called iPhone 8 and the phone's new 3D sensing capability, enabling users to create custom 3D animated emoji based on facial expressions picked up by the camera.
As noted by developer Steve Troughton-Smith, several Animoji will be available for customization using the iPhone 8's 3D sensing features, including chimps, robots, pigs, cats, poop, chickens, dogs, foxes, and several others unearthed in the software.
The range of expressions that the iPhone 8 will be able to detect are listed in a separate asset, showing off the level of detail the new camera feature is capable of reading on a human face. Animoji will be able to be customized using movement of the left and right eyebrows, cheeks, chin, eyes, jaw, lips, and mouth, with global detection for sad and happy faces.
Expect additional discoveries about the iPhone 8 and Apple Watch to be revealed soon as developers scour the iOS 11 GM code over the weekend. Apple will officially unveil the new devices at its Tuesday event set to be held at 10:00 a.m. Pacific Time.
