Where are the horizontal video characters in the grid?

The function of grid lines is to help photographers compose pictures. Taking portrait photography as an example, it will be dull to put people in the middle of the picture. Generally, people are placed in one third of the picture. If it is a close-up, the model's eyes should be in one third, so the grid line will play a role.

Most models have a grid line function on the display screen. When this display mode is selected, three horizontal lines and three vertical lines will appear on the display screen, which will divide the whole picture into nine squares on average, so it is called "grid line". The function is to help composition, mainly as horizontal and vertical lines.
