What are the highlights of shooting a video in the grassland with a halo in the morning?

It is a halo or halo formed by sunlight shining on fog or dew.

In the morning, when shooting a video in the grassland, the bright spots captured are halo, which may be the halo or halo formed by sunlight shining on fog or dew. This optical phenomenon is more common at sunrise and sunset, because the sun's rays are softer and can penetrate the atmosphere better, thus forming a beautiful light ring or halo.

Halo refers to the virtual shadow diffused from the edge of the developed image, and it can also refer to the time when strong light is projected on the film during exposure shooting.
