What lives in shadow evokes curiosity… then imagination fills the gap.

The creative use of light and shadow gives emotional depth to your story. Done effectively, it’s one of the most powerful tools a filmmaker can learn how to use.

Ever seen a shot and instantly felt a sense of drama, tension, or fear? There’s a name for this style and it’s called low key lighting.

What is Low Key Lighting?

Low key lighting is a visual style that emphasizes dark tones with high contrast and deep shadows. For the most part, there’s little or no use of mid-tones and ambient light. In fact, some call it shadow lead lighting.

For instance, you’ve seen it in genres such as dramas, thrillers, horror, and noir. It creates a closed-in effect, controlling the perception of the viewer.

This style is in direct contrast to high key lighting, which uses soft lights for a bright and evenly lit frame. This creates an open and positive atmosphere.

Low key lighting, on the other hand, uses hard light sources to create a stark contrast and deep shadows. With its concealing nature, it adds dimension and suspense.


Low key lighting has been around for a very long time, even before Film Noir. The evolution can be traced back to a style called Chiaroscuro from the Renaissance period.

Chiaroscuro Lighting

Chiaroscuro lighting

In Latin, ‘Chiaro’ – means clear or luminous, and ‘Scuro’ translates to ‘obscure or ‘dark’. Combining the two in one composition creates a bold contrast. As a result the subject pops, creating a 3-dimensional effect.

This famous style was popularized by great painters such as DaVinci, Caravaggio, and Rembrandt. DaVinci famously said:

“A painter should begin every canvas with a wash of black because all things in nature are dark except where exposed by the light.”

Chiaroscuro found its way into cinema during the German Expressionist movement a decade after WWI. This movement stepped away from being aesthetically pleasing, focusing more on a realistic view of the world.

As a result, the style thrived and inspired the well known genre – Film Noir. This classic lighting survived the introduction of color in motion pictures and is widely used in films we love today.

To help define the look, ask yourself simple questions: What is the tone of the scene?  What are the key aspects of the frame? What are the motives of the character?

Moreover, set design with low light is a bit easier than high key lighting.  Largely because unwanted details can hide in the shadows. In turn, equipment costs are low and setup time is fast.

How To Use Low Key Lighting?

First, in order to get the maximum contrast, your light sources need to be completely controlled.

Second, pay close attention to ambient light and white walls. Due to their reflectiveness, limit or eliminate.

Shooting in front of a setting sun makes for great silhouette shots. In the same way, In addition, street lamps or car headlights create menacing shadows.

Furthermore, you can establish opposing forces by using high key lighting in one scene, then low key lighting in the next. Remember that the purpose of your first shot is to get your viewer to watch the next. The first act to the final.

Step-by-Step Guide

Follow the steps below to create a dramatic shot with high contrast and deep shadows.

  1. First off, inspect all the details of the frame, your goal is to avoid shooting near white walls and ceilings. If needed, tape Duvetyne or black trash bags to the surface for negative fill.
  2. Next, Place your single source light behind your subject on the opposite side of your camera. Place light above your frame and angle slightly downward. To avoid creating a complete silhouette, bring the light slightly towards the side of your subject.
  3. If you have zero ambient light, set up a fill light to nearly an 8:1 ratio. Generally, you’re aiming for 3 f-stops or more between the key and the background of your subject. This will give depth to the shot. Check out our article on How To Use A Light Meter to learn about light ratios and f-stops.
  4. Use light modifiers such as barn doors or flags to trim the beam of your light source.
  5. Fine-tune the look of your shot using negative fill boards to the side or underneath your subject.
  6. Be sure to test the camera and character movement within the scene. Blocking may require tracking of your single source lights to maintain exposure on your subject. In addition, rehearse character gestures and props. The use of a second dedicated hard light may be required.
  7. To add an extra sensibility to your shot, add a little fill on the texture of the scene whether it’s dirt on the ground or grungy alleyway walls. Broken glass looks great too.

Pro Tips

Here are a few quick tips to help emphasize your low key lighting.

  • Smaller light sources create harsh lines, sharper edges, and shadows
  • Have your subject wear darker clothes and avoid patterns. This keeps the attention focused on the subject without creating unwanted fill light.
  • High contrast with soft edges is a stylistic choice. If this is what you’re aiming for, use a parabolic softbox with a grid. Grids are great to shape the direction of your light without spilling on the areas around your subject.
  • Haze spray or flour can also act as reflecting light, creating more of an atmosphere.
  • Save setup time by shooting at night. This drastically reduces your equipment list.
