A RAW file/image is used as the input to an editing process that results in a conventional image format such as JPG or TIFF.
In order to export your RAW images/files to a different device, such as your Mac or PC/laptop, you have different solutions.
1. Use iCloud Photos to access the original RAW files in full resolution on all of your devices.
2. To transfer the original RAW file from your iPhone to another iPhone, iPad, or your Mac, you can uus AirDrop.
3. If you edited the photo in the Photos app directly in the iPhone and then you share it, you'll share a JPG file. To share the original RAW file from the Photos app on your iPhone, tap Share, tap Duplicate, tap Edit, tap Revert, then share the photo using AirDrop.
4. To share an edited RAW 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 is shared.
5. To email a RAW photo, create an email in the Mail app on your iPhone, then add the photo to the email. The Mail app automatically converts the RAW file to a smaller JPG file, which you can then send with email.
6. If you edit a RAW photo and want to share both the original RAW file and the edited JPG file, use Image Capture on Mac or the Windows Photos app on a PC to import the files.
7. If you’ve edited a RAW photo in the Photos app on your Mac, and you want to use your Mac to share the original RAW file only, select the photo in the Photos app, then choose File > Export > Export Unmodified Original.
