Here's how Pixel users can access and use the new Night Sight feature
12

Night Sight, the new feature from Google that allows Pixel handsets to snap visible pictures under low-light conditions, is rolling out today. Last night, our Pixel 2 XL received the update to the Google Camera app that includes Night Sight (the changelist did not mention it). After installing the update, using the feature is pretty much, uh, a snap. First thing you need to do is open the camera app on your phone. Tap the "More" icon just above the shutter, and a little to the right.
When you are ready to take a picture using Night Sight, it is important that you do not move around. Clicking the shutter will also bring a pop up reminder to the screen, telling you to hold still while the photo is being taken. After you snap the shutter, the display will show a circle slowly being formed. Once the circle is complete, your photo is ready. The image on the top of the article shows a photo taken without Night Sight on the left. We used Night Sight for the photo on the right, and there is a stunning difference in visibility.

Night Sight is rolling out now to all Pixel phones
