 Astrophotography mode averages up to 15x 16-second exposures, to create a 4-minute exposure to significantly improve shot noise.Astrophotography activates automatically when Night Sight mode is enabled and the phone detects it's on a stable support.Astrophotography mode includes improved algorithms to remove hot pixels and warm pixels caused by dark current and convolutional neural network to detect skies for sky-specific noise reduction.
