Usually the camera can determine the exposure to shoot an object. But sometimes the camera is not always right. Exposure is determined based on the amount of light reflected by the object. Usually, if the object to be photographed is white, the camera will tend to lower the exposure because it is considered too bright, otherwise if the object is white, the camera will tend to reduce the exposure because it is considered too bright black is dominant, the camera will tend to increase the exposure because it is considered too dark.
So, we need exposure compensation to help adjust the exposure to what we want. However, this feature can only be used if you use manual mode, shutter and aperture priority, and program mode. This feature does not work in auto mode.
Increase exposure

In the image on the left, the camera refers to a light skin color, making the exposure darker so that the skin color looks dull.
In the image on the right, higher exposure compensation is used so that the skin color looks brighter as seen in the original.
Reduce exposure
Shooting with auto exposure - Shooting with exposure compensation -0.7EV
In the image on the left the camera refers to the color of the object as dark so the exposure is higher and the image looks too bright.
In the image on the right the exposure is reduced and makes the black look denser and stronger.
