"Turn off automatic HDR
By default, iPhone automatically uses HDR when it’s most effective. On some iPhone models, you can manually control HDR instead.
- On iPhone XS, iPhone XR, iPhone 11 models, iPhone SE (2nd generation), and iPhone 12 models: Go to Settings
> Camera, then turn off Smart HDR. Then from the camera screen, tap HDR to turn it off or on. - On iPhone 8, iPhone 8 Plus, and iPhone X: Go to Settings > Camera, then turn off Auto HDR.
- To turn HDR back on from the camera screen, tap HDR, then tap On."
