How to adjust your focus and exposure in iOS 14 or later

You can adjust your focus and exposure in iOS 14 or later. Before you take a photo, the camera automatically sets the focus and exposure, and face detection balances the exposure across many faces. 

You can use Exposure Compensation Control to precisely set and lock the exposure for upcoming shots.

Just tap the up arrow, then tap the +/- button and adjust your exposure level. The exposure locks until the next time you open the Camera app.

Exposure Compensation Control is available on iPhone 11, iPhone 11 Pro, and later with iOS 14 or later.
