Most of the scenes on The Cabinet of Dr Caligari were projected in low-key lighting together with the using of sharp tone lighting technique, creating the exaggerated contrast between light and shadow which is called optionally as “Chiaroscuro technique”. Throughout the film we can often see that the protagonists such as Dr Caligari, Cesare, or the narrator are mostly screened by sharpened shadows on their face which may represent their dark side identity or malicious inner mind of a man.
So we can see these unnaturally composited mise-en-scènes were frequently projected through distorted artistic elements.
