Use ProRAW with Photos and other apps
ProRAW uses the industry standard digital negative (DNG) file format, so you can open ProRAW files with apps that are compatible with DNG files. For the best experience, however, use apps that are compatible with ProRAW files, such as the Photos app on your iPhone with iOS 14.3 or later or on a Mac with macOS Big Sur 11.1 or later.
You can share the original unedited ProRAW photo, which has the .dng file extension. And if you edit the photo in the Photos app, you can also share the edited version, which has the .jpg file extension when shared.
Edit a ProRAW file with another app
You can open a ProRAW photo in an app that doesn’t support ProRAW, but it may look different than expected when opened. If the ProRAW photo doesn't look as expected, try using the app's feature for enhancing the photo automatically.
Share ProRAW photos
Here are the best ways to share your ProRAW photos:
- Use iCloud Photos to access the original ProRAW file in full resolution on all of your devices.
- To transfer the original ProRAW file from your iPhone to another iPhone, iPad or your Mac, use AirDrop. If you edit the photo in the Photos app and then share it, you'll share a JPG file. To share the original ProRAW file from the Photos app on your iPhone, tap Share, tap Duplicate, tap Edit, tap Revert and then share the photo using AirDrop.
- To share an edited ProRAW photo with someone else, edit the photo in the Photos app on your iPhone, then AirDrop, email or send with Messages. A JPG file that includes your edits will be shared.
- To email a ProRAW photo, create an email in the Mail app on your iPhone and then add the photo to the email. The Mail app converts the ProRAW file to a smaller JPG file automatically, which you can then send by email.
- If you edit a ProRAW photo and want to share both the original ProRAW file and the edited JPG file, use Image Capture on Mac or the Windows Photos app on a PC to import the files. You can also use AirDrop to share both files to a Mac. Tap on Options and turn on All Photos Data before sharing, then select Save to Downloads when you receive the files on your Mac.
- If you edit a ProRAW photo in the Photos app on your Mac, and you want to use your Mac to share the original ProRAW file only, select the photo in the Photos app, then choose File > Export > Export Unmodified Original.
