Use the camera settings on iPhone
Learn how to use Camera settings on your iPhone.
Align your shots
To display a grid on the camera screen that can help you straighten your shots, go to Settings > Camera, then turn on Grid.
On iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max, you can straighten and adjust perspective alignment in the Photos app. See Straighten and adjust perspective.
Preserve camera settings
You can preserve the last camera mode, filter, lighting, depth, and Live Photo settings you used so they’re not reset when you next open Camera.
Go to Settings > Camera > Preserve Settings.
Turn on any of the following:
Adjust the shutter-sound volume
Adjust the volume of the shutter sound using Ringer and Alerts settings.
Go to Settings > Sounds (Sounds & Haptics on models with system haptics). Or, mute the sound using the Ring/Silent switch. (In some regions, muting is disabled.)
