Google’s latest Pixel 3 and Pixel 3 XL smartphones were just unveiled this morning at an event in New York City. As expected, both phones are coming with a near-identical set of front-facing and rear-facing cameras that are powered by artificial intelligence. That allows them to do all sorts of algorithmic work behind the scenes in the form of new features, and it’s all powered by what Google calls its Pixel Visual Core chip.

Among the new AI features built into the Pixel 3 camera is two new shooting modes called Top Shot and Photobooth. Top Shot uses Google’s work in image and object recognition and computer vision to analyze photos and pick the best shots in a given batch. With Top Shot, you’ll be able to capture a number of photos before and after the moment you press the virtual shutter button, while the software will pick out the best shot. It’s similar to Google’s Motion Photos feature that creates GIFs from short snippets of video. You can still browse through the alternates to pick out others, Google says. Photobooth, like you might expect, takes a bunch of photos of you or your friends using the front-facing camera, but only when it recognizes that the subjects of the photo are making a funny face or smiling. You don’t need to even press the shutter.
