Question marked as
Are you asking about Shared Albums? (iCloud Photo Sharing - Apple Support)
You cannot change the ownership of a shared album. You can only unsubscribe from any shared album you subscribed to. Then create your own shared albums. Before you unsubscribe, import all photos you want to keep from the shared album. Delete all photos you added to the album.
To unsubscribe, select the shared album in the sidebar, then click the "People" button in the toolbar.
Then click the "Unsubscribe" button.
