Copying individual photos
In addition to copying albums or moments, you can also drag individual photos from the PowerPhotos image browser and drop them on another library in your library list to copy the photos and their metadata over. No albums will be recreated when doing this, but the photos will be automatically organized into moments by Photos based on their date and location.
To ensure that the extra photo information such as edits, titles, descriptions, keywords, dates, and favorites will come over, you should drag the photos from PowerPhotos’ image browser, and not from a Finder window or some other program that lets you drag files. If you drag from somewhere else, they will be treated as regular photos, and the extra information associated with them will not be brought into the destination library. It is also not possible to drag photos from the Photos app and drop them onto a library in PowerPhotos to copy them.
