Key takeaways
Three-point lighting uses a key light to shape the subject, a fill light to soften the shadows it creates and a back light to separate the subject from the background.
Start with the key light about 45 degrees to one side of the camera and slightly above eye level, angled down at the face.
Set the fill on the opposite side at roughly half the key's brightness, then adjust to taste. Less fill gives a moodier look, more fill a flatter, brighter one.
Place the back light behind the subject and out of frame, aimed at the hair and shoulders, so the subject doesn't blend into the background.
Match the color temperature of all three lights, or skin tones will shift between the lit and shadow sides of the face.
What you need
Three lights. LED panels or LED lights with softboxes are the easiest place to start, since they run cool and most let you set brightness and color temperature.
Three light stands, or clamps and arms if space is tight.
Diffusion, such as a softbox, an umbrella or a sheet of diffusion fabric, for the key and fill.
A camera on a tripod and a monitor or the camera's screen to check the image as you go.
Optional extras include a reflector, a dimmer or app control for each light and a grid for the back light.
Step 1: Place the subject and camera
Put the subject at least a meter or two in front of the background, which makes it easier to light them separately and stops their shadow from landing on the wall. Set the camera at eye level, frame the shot and switch off or block as much existing light as you can, including overhead lights and bright windows. Starting from a dark room means every light you add does a job you chose.
Step 2: Set up the key light
The key is your main and brightest light. Place it about 45 degrees to one side of the camera and 45 degrees above the subject's eye line, angled down toward the face. Look for a small triangle of light on the cheek on the far side of the face. This is the classic Rembrandt look, and it's a good sign the key is in the right place. Diffuse the key for soft, flattering light, and move it closer to the subject to make the light softer still.
Set the camera's exposure for the key light alone so the lit side of the face looks right before you add anything else.
Step 3: Add the fill light
The fill goes on the opposite side of the camera, at about the same height or slightly lower than the key. Its job is to lift the shadows the key creates, not to remove them. Start the fill at roughly half the key's brightness, a ratio of about 2:1, and adjust.
For interviews and talking-head videos, a gentle ratio of 2:1 to 3:1 keeps the face open and friendly.
For drama or a cinematic feel, drop the fill further or replace it with a reflector bounced back from the key.
If you see two shadows of the nose, the fill is too strong or too high, so lower its power or move it closer to the camera axis.
Step 4: Add the back light
Place the back light behind the subject on the side opposite the key, high up and out of the frame, aimed at the back of the head and shoulders. It creates a thin rim of light that separates the subject from the background, especially with dark hair or dark clothes against a dark wall. Keep it subtle. A back light that's too bright makes a glowing outline, and one that spills into the lens causes flare. A grid or barn doors help keep it controlled.
Step 5: Match color and check the result
Set all three lights to the same color temperature, such as 5600K for a daylight look or 3200K to 4500K for warmer interiors, and set the camera's white balance to match. Then check the image at full size.
The lit side of the face should not clip to pure white.
The shadow side should still show detail.
The subject should stand clearly apart from the background.
Catchlights, the small reflections of the key in the eyes, make the subject look more alive, so raise or lower the key until you see them.
Step 6: Light the background (optional)
Many setups add a fourth light for the background, such as a small LED aimed at the wall or a colored light behind a plant or shelf. It adds depth and gives a YouTube or interview set a finished look. Keep it dimmer than the subject so the eye goes to the face first.
Three-point lighting in a small room or with one light
In a small room, bounce the fill off a white wall or ceiling instead of using a second stand.
With one light, use it as the key and hold a white reflector or foam board on the other side as the fill.
A window can serve as the key. Place the subject at 45 degrees to it and add a lamp or LED behind them as the back light.
If the background is too close, turn the back light down and add a small background light instead to create separation.
Common problems
Harsh shadows on the face. Add diffusion to the key or move it closer to the subject.
Flat, lifeless look. Lower the fill so one side of the face is clearly darker.
Glasses reflecting the lights. Raise the key and move it further to the side, or tilt the glasses down slightly.
Shadow on the background. Move the subject further from the wall or raise the key.
Mixed colors on the skin. Turn off room lights and set all your lights to one color temperature.
Frequently asked questions
What is three-point lighting?
Three-point lighting is a standard setup for video and photography that uses a key light for the main illumination, a fill light to soften shadows and a back light to separate the subject from the background.
Where do you put the lights in three-point lighting?
Put the key about 45 degrees to one side of the camera and above eye level, the fill on the opposite side at lower power and the back light behind the subject on the side opposite the key, aimed at the head and shoulders.
How bright should the fill light be?
A good starting point is half the key's brightness, a 2:1 ratio. Use more fill for a bright, even look and less for a moodier, more dramatic one.
Can you do three-point lighting with two lights?
Yes. Use one light as the key and the other as the back light, and use a reflector or a white wall as the fill.
What color temperature should my lights be?
Use the same color temperature on all of them. 5600K matches daylight, while 3200K to 4500K gives a warmer look for indoor scenes. Set the camera's white balance to match.
