Cinematography lighting techniques refer to the techniques used by cinematographers for placing, controlling, and shaping lights to make scenes in movies look the way they should. The most common initial step would be three-point lighting, where key light, fill light, and backlight are used. Then cinematographers would move to other lighting styles such as low-key, high-key, Rembrandt, and motivated lighting.
Consider how it all goes down. Your camera captures light, not people and places. Even a very expensive camera would take a low-quality picture if the light is flat. Whereas an average camera can capture an amazing image if the light is not flat.
This guide would cover the following topics:
- good or bad light for the camera
- Three-point lighting step by step
- Different types of lights in cinematography
- low-budget cinematic lighting setups
- How to get started on a career with a cinematography course in Kerala
Why Is Lighting So Important in Film?
Lighting is essential because it dictates what will be seen by the audience, what they will see, and what they will experience emotionally through the visuals. The same two shots of an actor delivering the same line could be romantic or frightening, depending on the lighting!
Effective film lighting techniques will help you:
- Correctly establish the mood with proper lighting. Soft and warm lighting will create a safe environment, whereas the hard lighting will create tension and fear.
- Direct the viewer’s eyesight to the brightest point of the screen.
- Set the time of day and the setting. The morning sun will establish it is morning and outside; the tube lighting will indicate the time and place, inside an office or store; candle lighting will indicate the period and location, in an ancient Tharavad house.
- Creating depth. Lighting and shadows will help create a 3D effect on a 2D screen.
- The appearance of characters. The lighting reveals the face of the actor.
That’s why DoP is always so careful about lighting, which ends up in hours of effort when compared to the shot.
The Basics: Understanding the Quality of Light
Begin with learning the three properties of light: the strength, the direction, and the color of the light. Everything you know about the lighting techniques of film consists of different combinations of those three properties.
Hard Light versus Soft Light
Hard light emanates from a distant and small source and results in harsh and strong shadows. Picture overhead sunlight or a bare-bulb lamp. Soft light comes from a large source near your subject and creates soft shadows that dissolve gradually. Example: light during cloudy weather, light from a large window.
- Hard light is for tension, drama, heat, etc.
- Soft light is used in faces, interviews, romantic scenes and other scenes of daily life.
- Hard light can be softened by increasing its source. Use it as bounce light, reflect it into the white wall or diffuse it through a translucent white sheet.
Direction of Light
- The front light evenly illuminates the face, but the image appears flat.
- The side light adds some depth, texture, and form. This type of lighting is suitable for dramas.
- The backlight outlines the subject and separates him/her from the background.
- The top light is realistic outside but creates dark eye sockets.
- The underlight creates an unnatural lighting effect that is loved by horror films.
Colour Temperature
Every light source has its color, and it is measured in Kelvin (K). Tungsten lamps emit warm orange light (3200K), while daylight is cooler and has a blue tinge (5600K). Your camera’s white balance must be set according to your key light.
Here is a tiny hack. Intentionally combine warm and cool light, for example, an orange lamp inside a room and blue light of the moon through the window. It is one of the easiest ways to make your picture cinematic.
What Is Three-Point Lighting?
The three-point lighting technique involves the use of a key light, fill light, and backlighting that are arranged around the subject. The combination of these lights helps to create a shape for the subject, keeps the shadows under control, and separates the subject from the background. It is the first technique that a student studying films learns, since all other techniques are developed based on it.
Key Light
A key light is the strongest light and creates the overall effect and determines the direction of the shadow. It is placed at an angle of 30 to 45 degrees to the side of the camera and slightly above the eye level of the subject.
Fill Light
A fill light is located on the other side from the key light. It is less powerful than a key light and creates shadow areas on the subject. Its function is not to get rid of the shadows but to lighten them so that the viewer could notice the details.
Back Light
The backlight, which is sometimes known as rim light or hair light, is positioned behind the subject. It illuminates the subject with a fine line of light that runs around his or her head and shoulders. In its absence, the person dressed in dark clothing will vanish against a dark background.
Key Light vs. Fill Light
The key distinction between key light and fill light lies in this simple statement: The key light makes the shadows while the fill light dictates their darkness.
| Point | Key light | Fill light |
| Main job | Sets the look of the shot | Softens the shadows from the key |
| Brightness | Strongest light | Weaker, usually half or less of the key |
| Position | 30 to 45 degrees from the camera | Opposite side of the key |
| Controls | Direction and hardness of light | Contrast in the frame |
- The combination of both these elements is termed as lighting ratio.
- 2:1 ratio: Bright and even. Ideal for advertisements and corporate videos.
- 4:1 ratio: Natural and dramatic. Ideal for most scenes in movies.
- 8:1 ratio and higher: Dark and dramatic. Ideal for thrillers and scenes shot at night.
Three-Point Lighting Set-Up: How To Do It
For creating a three-point lighting setup, position the subject away from the wall, start by positioning the key light, followed by soft fill light from the opposite side, and finally the back light on the other side of the subject. Check the position of each light through the viewfinder of your camera before adding another light.
- Position the subject: Maintain a distance of around 4 to 6 feet of the subject to the background wall to prevent falling of shadow on the wall.
- Position the key light: Position it around 45 degrees from the camera angle, above eye level and pointing downward. The catchlights should be visible in the eyes.
- Fill light: This one goes on the other side of the camera, at lower power or at a greater distance. Turn it on gradually until you have the shadow side where you want it.
- Back light: Place this light behind your subject, above and opposite the key light, pointing to the head and shoulders of your subject and making sure that the light doesn’t go through the lens.
- Background light (optional): You can add some backlighting to the background by adding a small lamp or LED.
- Check and fix: Turn on and off each light in turn, checking your exposure with the histogram or zebras.
Three Point Lighting for Interviews
For three-point lighting in interviews, the person generally looks at the camera slightly from the side towards the interviewer. Position the key light on the side where they face. In this manner, the light will be shining on the front of their face, while the shadow side would be close to the camera, which looks more natural.
- Use a soft key light, such as a softbox or diffused LED light panel.
- Avoid having too harsh fill lighting; maintain a ratio of about 3:1 or 4:1.
- Hang a warm light in the background for a friendlier frame.
How to Set Up Three Point Lighting At Home?
Here you can learn to set up your three-point lighting at home without purchasing any studio lights.
- The key light can be a window allowing in the sunlight or a desk lamp with a sheet of white fabric in front of it.
- The fill light can be white chart paper, a foam board, or even a bedsheet that will reflect the key light back onto the face.
- The backlight can be an LED light bulb or phone torch, placed behind and above the subject.
One more thing. Turn off the ceiling tube lights before proceeding. Overhead mixed lighting is by far the most prevalent reason why home videos appear lifeless.
Types of Lighting Beyond Three-Point Lighting in Cinematography
After learning how to use three-point lighting effectively, you can move on to bending its rules. There are many types of lighting in cinematography currently in use, including high-key, low-key, Rembrandt, butterfly, split, loop, motivated, practical, and natural lighting. Every type of lighting evokes different emotions.
High Key vs Low Key Lighting in Films
The major distinction between high key vs low key lighting in films is the level of contrast. High-key lighting is characterized by high brightness and minimal shadows, while low-key lighting is the opposite, with lots of dark shadows.
- High-key lighting: Used in comedies, commercials, family films, and music videos. Has low ratio of illumination (about 2:1) and creates an airy, cheerful, pleasant atmosphere.
- Low key lighting: Used in thrillers, crime stories, horror, and noir. Has a high ratio of illumination (8:1 or higher) and creates dark, mysterious mood with the help of one single powerful light source and no fill light at all.
Probably, you have seen this effect in many crime thrillers, when an entire scene is lit up only by one lamp or a window with one side of the frame being dark.
Rembrandt Lighting Step-by-Step Guide
Rembrandt lighting is a popular type of portrait photography that takes its name from the Dutch painter. It can be recognised by a triangle of light on the cheek of the subject that is on the shadow side of the face. Below you will find step-by-step instructions on how to do Rembrandt lighting.
- Turn the subject’s face so that it faces the key light slightly.
- Place the key light about 45 degrees to the side and about 45 degrees above the head of the subject.
- Observe the shadow side of the face. There must be an intersection of shadows of the nose and cheek leaving a triangle of light under the eye.
- Move the light to the side if the triangle is too large, or raise it or move it to the front if there is no triangle.
- You can use minimal or no fill and reflectors for different effects.
Butterfly, Split and Loop Lighting
- Butterfly lighting: the key light source is high and placed directly in front of the subject’s face. The light creates a small “butterfly” shadow underneath the nose of the person. The lighting style is commonly used in beauty and glamour photography.
- Split lighting: the key light is positioned to one side of the face at an angle of 90 degrees to the face. As a result, exactly half of the face is illuminated. The style is dramatic and works well on trouble and villains.
- Loop lighting: the key light source is off-center and above the face. The nose cast shadow, creating a loop that goes toward the cheek. The lighting style is natural, flattering and common in interviews.
Motivated Lighting
Motivated lighting means that all light sources that exist in the scene appear as coming from an existing source be it a window, a street lamp, a television screen or fire. While you are using the film lights, you position them according to where the source should have been.
Practical Lights
Practicals are those lights which are shown in the scene itself. These include table lamps, fairy lights, neon signs, and the light tube at the tea shop. These provide depth and mood. They are also the source of motivation for your key lighting.
- Natural and Available Lighting
- Natural lighting is done using sunlight or other light sources available in the environment.
- Golden hour, the first and last hour of the sunlight, provides warm and low light.
- Blue hour, immediately after the sun set, provides a cool look.
- The window light on a cloudy day is one of the easiest ways to have soft light for free.
Lighting Techniques for Short Films and Videos
The best lighting techniques for short films are always those which are simple: motivated key light, a bit of fill or negative fill, and separation from the background. The short films are usually shot very fast by the crew, so those techniques which are easy to duplicate save much time.
- Lighting should be planned while scripting. The mood of each scene must be determined prior to the day of shooting.
- Keep light direction constant. When the key light is on the left side of the wide shot, then the same must be maintained in the close-up.
- Negative fill lighting technique. Placing a black cloth on the side where shadows are formed will add to the dramatic effect, and no extra lights are needed.
- The space must be lit, not only for the actors, so that people can move about easily.
- Test for 10 minutes. The ten minutes of testing will help save hours in the post-production process.
For YouTube video and head shots, a simple video lighting technique is sufficient which includes soft key, reflector for fill and background light. To be honest, video lighting techniques will do more for you than a new camera ever will.
Best Lights for YouTube Videos and Short Films
Three types of lights I consider “the best lights for YouTube videos and short films” for beginners include bi-colour LED panels, a COB light with a softbox, and two or three small RGB tube lights. With such equipment, you will be able to create a key light, fill light, backlight, and background illumination.
- LED panels: bright lights which feel cold and often run on batteries. Make sure that your LEDs are bi-colour in order to switch between warm and daylight settings.
- COB light with a softbox: one intense light source providing a soft and cinematic key light.
- RGB tube lights: perfect for backlighting, colouring the background or lighting practicals inside the frame.
- 5-in-1 Reflector: an inexpensive yet very useful tool for creating fill light and bouncing.
- Diffusion and flags: to soften light and control its spilling.
My quick tip for purchasing lights: pay attention to the CRI rating. The higher the number (more than 95), the more natural skin tones will look. Cheap lights with low CRI make faces slightly grey or green.
Low Budget Cinematic Lighting Setup
A low-budget cinematic lighting system doesn’t require expensive equipment. Consider this basic package, which is used by many students as a starting point:
- A window for the key light
- A bedsheet or butter paper for diffusion
- A thermocol or foam board for light bouncing to create fill
- A black cloth as negative fill
- A table lamp with a warm bulb for practical lights
- Phone torch or LED light as a hair light
- Stands (or even chairs), clips, and tape
Arrange your subject so that the window light hits him/her from the side position. Put the black cloth in another direction. Turn on a warm lamp in the background. This will be enough for a cinematic picture.
Common Mistakes and Tips: Cinematography Lighting for Beginners
Flat front lighting, mixing colour temperature and lack of separation between the subject and the background are the most common mistakes in cinematography lighting for beginners. However, all these errors can be easily corrected if you know how to spot them.
Mistakes to avoid:
- Front lighting for everything, destroys the depth of field.
- Keeping the ceiling tube lights on while filming
- Positioning the model against the wall
- Overshooting the face or the window behind
- Shifting the direction of light while filming the same scene
- Using five lights when a single light does the trick
A few simple tricks that come handy:
- Begin with a single light source. Adding further should always have a valid reason.
- Select a film frame and replicate it by recreating the lighting setup.
- Lighting the same face in five different setups and comparing the outcomes.
- Mastering the camera’s exposure tools such as the histogram, zebras and false colour.
