Apple's new high-end iPhone will make any traditional camera manufacturer tremble. The iPhone 11 Pro, unveiled at a special Apple event on Tuesday, not only has three cameras in the back--each having its own functions--but also for the first time utilizes artificial intelligence to take a photo. Yes, the next time you feel proud of snapping a perfect pic, it may have actually been the little robot living inside your phone. Here's how it works: On the iPhone 11 Pro, every time you are about to take a picture, the cameras will quickly take eight images of the object before you press the shutter. When you actually take a photo, the phone will compare your image against the eight previously taken ones and merge the best pixels of each image into one final product.
