How to measure light when taking pictures in moonlight?

In the moonlight, the actual brightness of the object is already very weak, which is beyond the actual working range of most exposure meters-1~19 or 20EV. At this time, only by giving full play to your own experience and understanding of exposure can you estimate the actual exposure, and at the same time, you should properly consider the working principle of the exposure instrument, which is less than one or two levels, in order to obtain a more on-site exposure.
