HDR camera on iPhone
HDR (high dynamic range) in Camera 
helps you get great shots in high-contrast situations. iPhone takes several photos in rapid succession at different exposures and blends them together to bring more highlight and shadow detail to your photos.
By default, iPhone uses HDR (for the rear camera and front-facing camera) when it’s most effective. For best results, keep iPhone steady and avoid subject motion.
Turn off automatic HDR
By default, iPhone automatically uses HDR when it’s most effective. To manually control HDR instead, do the following:
On iPhone XS, iPhone XS Max, and iPhone XR: Go to Settings
> Camera, then turn off Smart HDR.To turn HDR back on from the Camera screen, tap HDR, then tap On.
On iPhone X, iPhone 8, and iPhone 8 Plus: Go to Settings > Camera, then turn off Auto HDR.
To turn HDR back on from the Camera screen, tap HDR, then tap On.
Other models: Tap HDR at the top of the Camera screen, then tap Off.
Keep only the HDR version of a photo
By default, the HDR version of a photo is saved in Photos, but you can save both the HDR and non-HDR versions.
Go to Settings > Camera, then turn on Keep Normal Photo.
Tip: In your albums, HDR versions of photos are marked with “HDR” in the corner.
