Why are the skin colors taken by foreign photographers very positive?

Skin color is the most difficult in photographic color expression, because there is a clear reference, and a slight deviation will be detected.

In color photography, if you want to express people's skin color well, you need to control in several aspects, one is the choice of lighting equipment (or natural light), and the other is the setting of camera's white balance, which is the most important. The color correction of display and the color expression of printed publications are both important links in computer image processing in the later stage.

Foreign photographers are strict in these aspects, so the skin color of the final photographic works is more accurate.
