How to Light an Interview: A Setup That Works Anywhere

To light an interview, seat the subject a few steps away from the background and set their eyeline just beside the lens. Put a large, soft key light on the far side of the face, so the shadow side turns toward the camera. Then control contrast with fill or negative fill, add a small backlight, light the background on its own, match color temperatures and set a flicker-safe shutter. This guide is part of our video production guide.

You'll need two or three lights, diffusion, a black flag or fabric, and a camera with manual exposure. Plan power and window positions on the scout, using our pre-production checklist.

What good interview lighting does

Interview lighting has three jobs. It shapes the face so it looks three-dimensional, not flat. It separates the person from the background so the eye goes straight to them. And it stays consistent for the whole interview, so every answer cuts with every other.

The classic tool is three-point lighting: a key, a fill and a backlight. The most flattering version for interviews uses a large soft key off to one side of the camera, with the shadowed side of the face closer to the lens. Cinematographers call it "shadow side to camera". It gives shape to the face, and it matches the natural eyeline of a subject talking to someone just off camera. We explain each light's job in three-point lighting.

The interview setup at a glance

Each light in the setup has one job. Here's where each one goes, before the step-by-step detail:

Steps

1. 01
   Pick the spot and pull the subject off the wall.

   Choose a background with some depth, and seat the subject well away from it, with the camera at an angle to the walls rather than square to them. A subject pressed against a wall looks flat, and the key light lands on the wall as well. Distance gives you room to light the background separately and let it fall darker or softer.

2. 02
   Set the eyeline and the camera.

   Seat the interviewer right beside the lens, at the subject's eye height, so the eyeline lands just off camera. That side of the lens becomes the subject's "near" side. Set the camera at eye level. If you add a second camera, keep it on the same side of the 180-degree line between the subject's eyes and the interviewer, so the two angles cut together.

3. 03
   Place the key on the far side.

   Put the key light on the side of the subject's face away from the camera, a little in front of them and above eye level, angled down. Now the side of the face toward the lens falls into soft shadow, which gives the face shape. Raise or lower the key until you see a small catchlight in both eyes and no harsh shadow under the nose.

4. 04
   Make the key soft with size and distance.

   Softness comes from how big the source is relative to the subject. A large diffusion frame or softbox brought close gives soft, gradual shadow edges. The same light pulled far back gets harder. Diffusion only softens when it makes the source bigger, so clipping a small piece to the front of a fixture does little. Bring the key in as close as the frame allows.

5. 05
   Control contrast with fill or negative fill.

   Look at the shadow side of the face. To lift it, add a white bounce or a dim light on the camera side. To deepen it, hang black fabric or a flag there instead. On location, white walls often bounce in more fill than you want. Remember the inverse-square law: double a point source's distance and the light falls to a quarter, two stops darker.

6. 06
   Add a backlight for separation.

   Place a small, dimmed light behind the subject on the side opposite the key, high and out of frame. It should put a thin edge of light on the hair and shoulders, not a glow. Flag it so it doesn't flare into the lens. A backlight matters most with dark hair or clothes against a dark background, where the outline would otherwise disappear.

7. 07
   Light the background on its own.

   Light the background separately, with a small fixture, a practical lamp in frame or simply by controlling what the key spills onto. Keep it darker than the face so the eye goes to the subject. A slightly cooler background behind a slightly warmer subject adds depth through color as well as brightness.

8. 08
   Match color temperature and check light quality.

   On location you'll often mix daylight from windows with warm room lights. Pick one balance and bring the others to it. Set bi-color fixtures to match, or gel tungsten with CTB to approach daylight, or daylight sources with CTO to approach tungsten. Turn off sources you can't match. When choosing LED fixtures, look for published TLCI or SSI scores, which measure how a light renders on camera.

9. 09
   Lock exposure and kill flicker.

   Set white balance, shutter, aperture and ISO manually so nothing drifts during the interview. Expose for the skin on the key side, using false color or a waveform if your monitor has one. Under 60 Hz mains power, a 1/60 or 1/120 shutter avoids most flicker, because many lights pulse 120 times a second. Record a test clip and play it back before rolling.

If you'd rather leave the lights to a crew, our in-house video production team handles camera, lighting and sound on every shoot, with no handoffs. Sound needs the same care: see how to record clean audio on location.

Using a window as the key

A large window is a big, soft key light that costs nothing. Seat the subject so the window is in front of them but off to one side, on the far side of the face from the camera, and the shadow side falls toward the lens on its own. Add black fabric on the camera side if the room bounces too much light back in.

Windows come with three catches.

First, daylight changes. Clouds can shift exposure and color in the middle of an answer, so watch the monitor and be ready to adjust. For long interviews, many crews add a matched light so they aren't left depending on the weather. Second, anything visible through a window that appears in frame, such as traffic or people walking past, will pull the eye. Third, daylight from the window and warm room lights won't match, so switch off the room lights or bring them to the window's color.

Troubleshooting

Reflections in the subject's glasses

Cause: light bounces off a lens at the same angle it arrives, so a key placed near the camera axis reflects straight back into the lens. Large soft sources are especially easy to see in glasses, because they cover so much of the reflected view.

Fix: move the key higher and further to the side until the reflection slides out of the lens, checking on the monitor rather than by eye. Small changes in the light or the subject's head angle make a big difference. If that isn't enough, ask the subject to tilt the frames very slightly down at the temples. If reflections from bright windows or white walls remain, flag those surfaces or turn the subject slightly away from them.

Flicker or rolling bands in the footage

Cause: many artificial lights pulse at twice the mains frequency, which is 120 times a second on 60 Hz power. If the shutter speed doesn't divide evenly into those pulses, each frame catches a different amount of light. Some LED fixtures and screens flicker on their own cycle, separate from the mains.

Fix: set the shutter to 1/60 or 1/120 under 60 Hz power, or 1/50 or 1/100 under 50 Hz power, and record a test clip. If a light still flickers, change its dimming setting or flicker mode, replace it, or switch it off. Avoid high frame rates under artificial light unless you've tested them. Check practical lamps and screens in the background, too.

Skin looks green or magenta

Cause: the light sources don't match, or one of them has a spiky spectrum that the camera renders badly. Fluorescent tubes and some LED fixtures add a green or magenta tint that white balance alone can't fully remove, especially when they are mixed with daylight or tungsten.

Fix: turn off overhead fluorescent or LED room lights wherever you can, and light the face with fixtures you trust. Use the green-magenta (tint) control on bi-color or RGB fixtures where available. When buying lights, compare published TLCI or SSI results, which describe how a light renders on camera rather than to the eye. Then white-balance on a gray card under the key, and check skin on a calibrated monitor.
