Now, some Pixel 4 users have discovered that the same feature can be used to capture stunning light trails. This week, a few examples have surfaced on Reddit, Twitter, and YouTube which show what happens when you introduce moving lights to this mode.
Using the Astrophotography feature on the Pixel 4, YouTuber Matt Gonzalez shared an absolutely stunning shot taken in the desert where a light trail is visible near the bottom of the shot, presumably from a passing vehicle.
In another shot taken with the Pixel 2 and a modified Google Camera app, a user on Reddit also shared a shot that showed light trails from vehicles passing on the highway.
