How to focus with my camera iPhone 13 Pro

Hi carriefromreno,

Thanks for contacting Apple Support Communities!

We understand that you'd like to learn how to focus using your iPhone camera.

You can tap on the subject in your photo preview to focus your shot. You can learn more about the features of your camera here: Use iPhone camera tools to set up your shot

"Adjust the camera’s focus and exposure

Before you take a photo, the iPhone camera automatically sets the focus and exposure, and face detection balances the exposure across many faces. If you want to manually adjust the focus and exposure, do the following:

1. Open Camera.
2. Tap the screen to show the automatic focus area and exposure setting.
3. Tap where you want to move the focus area.
4. Next to the focus area, drag  up or down to adjust the exposure.

To lock your manual focus and exposure settings for upcoming shots, touch and hold the focus area until you see AE/AF Lock; tap the screen to unlock settings.

On iPhone 11 and later, you can precisely set and lock the exposure for upcoming shots. Tap , tap , then move the slider to adjust the exposure. The exposure locks until the next time you open Camera. To save the exposure control so it’s not reset when you open Camera, go to Settings  > Camera > Preserve Settings, then turn on Exposure Adjustment."

We hope this helps.

Cheers!
