Q: In Photos.app I have stored images with adjustments. How can I back them up non-destructively to the Finder?
The adjustments were applied exclusively with the built-in Photos.app in iOS 10 and iOS 11. They include image crop, image rotation and color adjustments.
Copying from iPhone to Mac works fine
Copying photos from an iOS device (iPhone, iPad) results in an .AAE sidecar file in addition to the unmodified photo. E.g. IMG_1234.jpg and IMG_1234.aae. The .AAE sidecar file contains all modifications applied by Photos.app to the image (crop, color adjustments, markups).
Importing the image with the corresponding .AAE file to Photos.app for macOS will apply all adjustments to the image in Photos.app.
Issue: Copying from macOS Photos.app to Finder
File > Export > Export Unmodified Original For 1 Photo in Photos.app
results in the unmodified image. This is what I want, except for the missing adjustments.
The feature I am looking for was called "Relocate Originals..." in iPhoto/Aperture.System specs
macOS 10.13 High Sierra, Photos.app photo library is linked to iCloud storage
