Take a photo in Portrait mode

On iPhone 8 Plus, iPhone X, and later, you can apply studio-quality lighting effects to your Portrait mode photos.

1. Open Camera, then select Portrait mode.
2. Follow the tips onscreen to frame your subject in the yellow portrait box.
3. Drag  to choose a lighting effect:

• Natural Light: The face is in sharp focus against a blurred background.
• Studio Light: The face is brightly lit, and the photo has an overall clean look.
• Contour Light: The face has dramatic shadows with highlights and lowlights.
• Stage Light: The face is spotlit against a deep black background.
• Stage Light Mono: The effect is similar to Stage Light, but the photo is in classic black and white.
• High-Key Light Mono: Creates a grayscale subject on a white background (available on iPhone XS, iPhone XR, and later).

4. Tap the Shutter button to take the shot.

After you take a photo in Portrait mode, you can remove the Portrait mode effect if you don’t like it. In the Photos app, open the photo, tap Edit, then tap Portrait to turn the effect on or off.

Note: On iPhone 12 Pro, iPhone 12 Pro Max, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 14 Pro, and iPhone 14 Pro Max, Night mode turns on when you take a Portrait mode photo in low-light situations with the wide (1x) lens. To learn more about Night mode, see Take Night mode photos.

Note: On iPhone XR, Stage Light, Stage Light Mono, and High-Key Light Mono are only available when you use the front camera.

Adjust Depth Control in Portrait mode

On iPhone XS, iPhone XR, and later, use the Depth Control slider to adjust the level of background blur in your Portrait mode photos.

2. Tap  in the top-right corner of the screen.
3. The Depth Control slider appears below the frame.
4. Drag the slider to the right or left to adjust the effect.
5. Tap the Shutter button to take the shot.

After you take a photo in Portrait mode, you can use the Depth Control slider in Photos to further adjust the background blur effect. See Edit Portrait mode photos.

3. The Portrait Lighting slider appears below the frame.
