Users can toggle low light mode, which senses poor lighting conditions and boosts the image's exposure to create a clearer video call. Details on how this is achieved are scarce, but Google does mention that results will differ based on the environment and the device being used. The update will be rolling out on iOS and Android this week. Google Duo is also available via Chrome, but it sounds like low light mode will be an app-exclusive feature.

Google has been heavily focused on improving low light image quality lately. The Night Sight camera mode featured in their Pixel phones is surprisingly powerful, capturing bright, sharp, and color-accurate photos without the need of firing the camera's flash. Google didn't say if Duo is using similar technology, but it's definitely looking to achieve the same effect here.
