How to use light to analyze the characters in the movie "800"

Gao Fancha used a lot of contrast between light and shade to dilute the surrounding environment, highlighting people's faces, especially their eyes, and showing the psychological changes of soldiers in despair. Throughout the 800-mile photography, both color and light are exquisite. The pan-green tone and excellent light ratio constitute the visual tone of the film, and the excellent soundtrack conveys a tragic atmosphere.
