The front-facing TrueDepth camera is crazy powerful
As impressive as the rear-facing dual lens system is, it's the X's front-facing TrueDepth camera that steals the show. Packed inside the small notch at the top of the newly bezel-less screen is a complex camera system that serves as the foundation for the new Face ID feature, and consists of a dot projector, infrared camera, and flood illuminator, all of which work in tandem to rapidly map and authenticate your face.
Besides scanning your face to verify you are indeed you (and create custom animated emojis that capture your unique facial expressions), the 7MP front-facing camera is also a damn good camera for, well, shooting selfies. In fact, it not only boasts auto image stabilization to help you snap sharper shots, but also now supports Portrait Mode. Yep, that means you can now take exceedingly dramatic selfies using the Portrait Mode's depth effect.
