In most conditions whether it be low light or bright natural light the Pixel 2 takes incredible photos with natural yet vibrant colors, industry leading dynamic range, and unmatched clarity. That being said the camera is exhibiting some strange behavior under LED lighting. Some users are experiencing odd banding if an LED light is in the shot. This could be quite annoying if an LED light just happened to be behind your subject as the shot is ruined entirely with the banding.
The banding effect is similar to what you might see when trying to take a photo of a TV. Apparently LED lights flicker at the frequency of alternating current. The flickering can not be seen by the human eye but can be seen by some cameras. This is not an issue with the OG Pixel, but apparently is on both the Pixel 2 and Pixel 2 XL. So far there is no word on a fix although Google has responded to complaints by saying this issue will be sent up the chain of command. Hopefully this will be fixable with an update otherwise try to stay away from LED lighting when taking shots with your new Pixel 2.
