Taking pictures in low-light situations has always been a challenge, especially on smartphone cameras.
For now, the Night Sight feature for the Google Camera app is only available for Pixel and XL, Pixel 2 and 2 XL, Pixel 3 and 3 XL. But when you actually shoot a picture, it's not a simple click and you're done.
Google says to expect it on your phone (all Pixel phones) in the next couple of days, thanks to an update to the Google Camera app.
Update:11/14/2018: Google responded to Gizmodo and said: "we recently discovered a bug affecting SMS/MMS on a small number of Pixel 3s and are rolling out a fix soon".
It appears that issues continue to affect Pixel 3 devices after the latest security updates pushed out by Google. The camera app will even suggest when you should give Night Sight a shot - you can find it under "More" and then choosing "Night". Otherwise, it uses shorter exposures to minimize blur.
Optical image stabilization (OIS), which is present on Pixel 2 and 3, reduces handshake for moderate exposure times (up to about 1/8 second), but doesn't help with longer exposures or with moving objects. In the dark, you get crisp details without excessive noise.
What's more exciting is that the Night Sight feature works on front cameras as well. I'm personally not a fan of using LED flash on smartphones for clicking in low-lights as it would eliminate the natural element, but what Google does with the Night Sight is mind-blowing. But in extremely low-light situations in which no other smartphone camera is up to the task, Night Sight shines. Both Pixel 3 and Pixel 3 XL features a 12.2MP primary camera and dual 8MP front-facing cameras. Google also does extensive tone-mapping, which makes the images pop a bit more and gives it that Pixel look.
Here are a handful of additional Night Sight comparisons.
