Excuse me, how does Apple's mobile phone shoot the track of stars?

Excuse me, how does Apple's mobile phone shoot the track of stars? Apples should not work. Apple was not exposed for 30 minutes. Although the pixel quality is ok, it is not enough to shoot the star trajectory.

The reason why Apple can't photograph the track of stars: Transparency is an essential feature of successful star-orbit photography.

With the rotation of the earth, the stars in the night sky will leave traces of different lengths in the shooting results obtained by long-term exposure. In the background of buildings, trees and other ground scenery, we get refreshing works. The special effect of this kind of star-orbit photography can't be achieved by other types of night photography.

To shoot idolize photography, we must first find the North Star in the sky. Strictly speaking, it is not the central axis of the star's revolution, but it can be used as our reference. The spoon-shaped Big Dipper and the W-shaped Cassiopeia are distributed on both sides of Polaris, and they are both reference objects for finding Polaris. Set the camera sensitivity to ISO 1600-3200, and use a larger aperture to check the focus.

And Apple obviously has no such requirement!
