What filter does the drone city use to shoot the night scene?

The upper part of this filter is gray-black, and the lower part is transparent, with a natural transition between the two parts. We can use gradient filters to shoot the sky. The gray in the upper part filters out some light and darkens the sky, while the transparent part will not reduce the exposure of the scenery below the sky, which is beneficial to outdoor landscape shooting.

Mainly suitable for shooting long shots with fixed angles, time-lapse photography, single-leaf scenery and other scenes. Gradient gray is mainly used to save the dynamic range of small-size cameras. When shooting night scenes for a long time, it can also be used to darken the city sky under light pollution.
