perhaps the most common lighting scenario is to use an on-camera flash as the fill light, and sunlight as the main light.

thus far we've focused on scenarios where natural light is the main light source, and the camera's flash is used as the fill light.

到目前为止我们已经关注情况下自然光线是主要的光源，相机的闪光灯作为填充光。

the numbers are sometimes also reversed, but the smaller number always refers to the fill light.

这些数字都是有时也逆转，但始终是指数量较少的填充光。
