The Inspiron 15 5000 Series also features the Intel RealSense 3D Camera Front F200. Intel's RealSense technology uses three cameras to measure image depth and the shape of objects in photos. The tech allows the focal point to be shifted after an image is taken and other neat photo-editing tricks, as well as 3D scans of people and objects to be created. It can also be used for gesture and facial expression recognition.
