ACDSEE, please say in ordinary people's language: What's the difference between color scale and brightness and exposure?

Color scale: There are many things that can be adjusted, such as how dark the dark place needs, and the bright place needs how bright, which can be adjusted according to your own preferences.

Brightness: If you like this picture, there will be how bright and how bright. Its function is less than color code, that is, dark places and bright places are bright and dark at the same time.

Exposure: It's like a picture of how badly the sun shines. Well, one word is emphasized here, Sun. The difference between brightness and lightness is that lightness is to increase the brightness of your photo by adding white to it. But the exposure is like something in a photo getting sunburned instantly, and the real lighting effects is obvious.
