The camera is one of the key features that drives smartphone purchases. As a result, device makers have been investing a lot of their energy there.

One form this has taken is the addition of multiple lenses on the rear of the camera, offering a bit of zoom or an extra-wide angle.

But the real advances have been in what smartphones can do with the images they capture. By passing data from multiple lenses and mutiple exposures through their high-end proccessors, today’s phones can create stunning portraits, freeze fast-moving action, make sunsets and fireworks a snap — and even change the focus after a portrait is taken.

Indeed, the low-light capture has gotten so good that smartphones can take pictures that make night seem like day or illuminate a an almost dark room.
