Why your Mac camera looks dark, and how to fix it
By A.C.R. van Hooff Updated 5 min read
Short answer: Apple’s cameras set their exposure by themselves, and macOS has no brightness or exposure setting. The camera measures the whole picture, so a bright window behind you or a dim room leaves your face too dark. Fix the light first. For real control over exposure, shadows and colour, use an app that adds its own camera to macOS, such as Camerture.
Why your Mac camera looks dark
The camera in your MacBook, iMac or Studio Display decides on its own how bright the picture should be. It measures the light in the whole frame and aims for an average. That works when the light is even, and goes wrong in two very common situations.
A bright window or lamp behind you. The camera sees a lot of light, darkens the whole picture to keep the window from turning white, and your face ends up in the shadow. This is the classic backlit video call.
A dim room. With little light, the camera raises its sensitivity. The picture gets brighter, but also grainy, soft and flat, and in the evening it often still looks dark. Laptop cameras have small sensors, so they struggle with this more than a phone or a real camera.
Why it can look washed out instead
The opposite happens too: a pale face, grey blacks and no contrast.
- The camera exposes for a darker background. Sit in a pool of light in a dark room and the camera brightens everything for the room, so your face turns too bright.
- A smudged lens. A fingerprint on the camera glass makes the whole picture hazy and soft, with glowing highlights. On a MacBook it happens every time you open the lid by the top edge.
- Mixed light. Daylight from a window and a warm lamp at the same time confuse the automatic white balance. You end up orange on one side and blue on the other, or with a colour cast over everything.
Why you can’t just turn up the brightness
macOS has no camera settings. There’s no exposure, brightness or white balance for the camera anywhere in System Settings, and that’s not a hidden option you missed.
Apps can’t change the camera’s own settings either. The built-in FaceTime HD camera and an iPhone used as Continuity Camera have no settings that other apps can reach. The Studio Display’s camera has no exposure or colour settings for apps, apart from switching automatic white balance on or off and a flicker setting. That’s why the webcam settings apps you find for Mac only work with USB webcams: they change settings inside the camera, and Apple’s cameras don’t offer any. Mac camera settings apps compared explains the difference.
What does work is changing the picture after it leaves the camera. That’s what macOS’s video effects, your call app’s own settings and apps like Camerture do.
How to fix a dark Mac camera
Start at the top: the first fixes are free and help with any camera.
1. Fix the light
Light makes the biggest difference, and it costs nothing.
- Face the light. Turn your desk so the window is in front of you or beside you, never behind you. If it has to be behind you, close the curtain during calls.
- Put a soft light behind your screen. A desk lamp pointed at the wall behind your Mac, or at a sheet of white paper, lights your face evenly without glare.
- Light at eye level, not from above. Ceiling lights put shadows under your eyes. A lamp at face height looks far better.
- Use one kind of light. Either daylight or lamps, not both. If you mix them, a daylight-coloured bulb helps.
2. Clean the lens
Wipe the camera glass with a soft, dry cloth, such as a glasses cloth. If the picture looked hazy or soft, it may be all you needed.
3. Try Studio Light in macOS
During a call, click the camera icon in the menu bar or in Control Center to open the video effects. Depending on your Mac and camera, macOS offers Portrait, Studio Light and Center Stage. Studio Light dims the background and brightens your face, which helps against a window behind you. It’s free, but it’s a single effect: you can’t set the exposure, the shadows or the colour.
4. Use your call app’s own setting
Some call apps have their own fix. Zoom, for example, has “Adjust for low light” in its video settings. These only work in that one app, and they’re different in every app.
5. Use your iPhone as a webcam
With Continuity Camera, a recent iPhone works as your Mac’s webcam. Its camera is much better in low light than a laptop camera. You do need to mount the phone above your screen for every call.
6. Adjust the picture yourself with Camerture
Camerture adds the settings Apple left out: exposure, contrast, highlights, shadows, temperature, tint, saturation, vibrance, skin redness, sharpness and zoom. It adds its own camera to macOS, so you pick “Camerture” once in FaceTime, Zoom, Teams, Meet or any other app, and they all get the adjusted picture. It works with the built-in camera, the Studio Display, Continuity Camera and USB webcams, remembers your settings for each camera, and processes everything on your Mac. Setting it up takes about a minute; it’s a one-time purchase of $14.99.
Settings that fix common problems
If you use Camerture, these are good starting points. Make small changes and compare with the live preview.
| Problem | What to change |
|---|---|
| Face too dark, window behind you | Raise Shadows, raise Exposure a little, lower Highlights |
| Dark, grainy picture in the evening | Raise Exposure and Shadows, keep Sharpness low so the grain doesn’t stand out |
| Washed out, pale face | Lower Exposure and Highlights, raise Contrast a little |
| Orange or yellow picture under lamps | Move Temperature towards blue |
| Red face or blotchy skin | Drag Reduce skin redness to the left (see why your face looks red) |
Questions
Can I change the exposure of my MacBook camera in System Settings?
No. macOS has no exposure, brightness or white balance setting for any camera. You need to change the light, or use an app that adjusts the picture.
Will a better webcam fix it?
Partly. A good USB webcam has a bigger sensor and settings you can change, so it copes better with dim light. But it still can’t do anything about a window behind you, and many people would rather keep using the camera they already have. Camerture works on both.
Do I need to keep Camerture open during calls?
No. The Camerture camera remembers your settings and keeps using them, even when the app isn’t running. Nothing is recorded or uploaded: every frame is adjusted on your Mac on its way to your call.
