ring light for sale

In many shooting tutorials, everyone has taken "never owe" to the correct method of shooting. Later, someone suggested that "Ning owe not to expose" is the filming experience of the film era, which is outdated. On the contrary, on a digital camera, it should be "not exposed to owe" and should be exposed to the ring light for sale right. What do you think of this problem?
If the dark side of the picture is mostly bright, it is ok to expose to the right, and the data taken is larger than the left exposure. If the picture is bright, on the contrary, the photo is taken to the left and the photo data is larger. In the shooting, you still need to follow up the situation to deal with.
For example, in the following scene, if we are exposed normally, the details of the sky will be completely gone, let alone the exposure to the right. This kind of sky can't be pulled back later.
