Chiaroscuro is an Italian world that literally means ‘light-dark’ and is a visual technique that was first used by Baroque painters. It was a form of studio lighting that would cast harsh shadow and design volume and forms.
It was later applied to photography and eventually to cinema.
To a certain extent, the use of chiaroscuro in film noir was a necessity. Many of these films where made on a budget and didn’t have a great possibility of using lavish sets. Lighting only a part of the set helped to save money on lighting as well as using shabbier sets that would be concealed by the shadows and only partially revealed by the light when and where needed.
When Hollywood decided to go noir, there were no greater masters of chiaroscuro then the Germans, so it’s no surprise that so many Germans and East Europeans, newly arrived to America as expats, worked on these films.
These cinematographers cast an expressionist shadow on the realistic setting, populating it of oblique and vertical lights and sharp shadows that often came from just one source of light. This created a very specific mood. Oblique lights tend to split the screen, making it restless and unstable.
The actor and the setting were
normally given equal light emphasis, which took away from the characters to give the environment where they moved a greater weight. This created an overwhelming sense of unbalance and uncertainty that perfectly expressed the message of these films.
The Stranger on the Third Floor is a prime example of how chiaroscuro could be used for emotional effects. Cinematographer Nicolas Musuraca creates a world of high light and shadow and uses unique camera angles. His light is deliberatly artificial, it emphasises deep shadows and sharp contrast to create a world that, although perfectly recognizable, also carrys many characteristics of the fantastic.With chiaroscuro, #FilmNoir turned a limit into one of its strengest points #AtoZChallenge Click To Tweet
Ultimately, film noir turned its limit into its greatest strength. Born out of necessity, the use chiaroscuro lighting is now one of the most recognizable characteristic of film noir in all its forms.
