Who needs a telephoto lens? The Google Pixel 2 will make Portrait Mode photos with a single camera21
Now, what's important to note is that Apple uses information from both the regular camera and the telephoto lens one in order to get the depth information needed for Portrait Mode to do its magic. The feature has been emulated by some apps and some device manufacturers, but without 2 cameras, it's sketchy to get it to work. Samsung did add it to the Note 8 since it also has a dual camera module on its back.
Pixel technology of the camera sensors it uses. Each pixel in the sensor is comprised of two separate pixels — a feature, which helps with light collection and fast focus. Now, Google has added an algorithm, which analyzes the information from the Duo Pixels to create a depth map.
A depth map is, of course, the information on background, foreground, and different object distance within an image. So, using that map, the Pixel 2 and Pixel 2 XL will be able to simulate the natural blur of a pro camera, or at least it's supposed to.
The Portrait feature will also be available for selfies, since the camera up front also has a dual pixel sensor.
Google claims this tech works great, we are a bit skeptical. But we certainly can't wait to try it in a couple of comparisons.
