Sell shoelaces live. Why is there a big light gap? What is it?

Because four kinds of lights are used.

Live broadcast uses four kinds of lights together, namely:

1, main light. As the name implies, it is the light that hits the anchor or the whole body. Generally, it is to whiten and thin the face of the anchor, which has the effect of soft light and beauty. The side lights on both sides are placed at different angles, which can create a layered and three-dimensional sense of the anchor.

2. Backlight. Putting it behind the anchor is also to highlight the anchor, reduce the integration with the background and make the anchor look more three-dimensional.

3. dome light. It's the light from the anchor's head, a bit like a spotlight.

4, fill the light. It is floor-standing, and the whole light box is placed on the ground.
