下面有一位回應說在電影課上寫了一篇就是比較戲內光影對照角色的運用：In my film class I did a paper on the difference in lighting between Lex at the beginning and at the end of the film. This is the point where during the same scene he goes from soft front lighting to hard overhead lighting, which like you said, shows his true self.
Interestingly enough, Lex’s character and Bruce switch lighting effects during the film. Further illustrating how Bruce is saved at the end! It makes the film that much more detail oriented.
