PRO TIP! SAVE BOTH HDR & STANDARD VERSION OF PHOTOS
On the iPhone, you can turn on a setting that saves both the HDR and standard version of a photo so you can compare later without having to worry ahead of time about whether or not HDR will improve your shot. Keep in mind, however, that saving both takes up more storage on your iPhone, unless you're willing to go through your photos regularly and delete the version you don't want to keep.
To save both the normal and the HDR version of photos on your iPhone: • Open Settings. • Tap Camera.
• Scroll down to HDR (High Dynamic Range). You'll see the option to Keep Normal Photo. Toggle it on to save both the HDR photo and the non-HDR photo.
