Copying individual photos
In addition to copying albums, 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 copying individual photos this way.
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, the Photos app 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 from Photos will not be brought into the destination library.
