You have lost me I am afraid. It is a long exposure taken during the night (on this occasion a full moon) and the lines were made using LED lights. It is 100% a light painting, with no tampering involved.
Love This..!! I don't know how you did this but I love light painting, have been trying it out a little myself but this looks like it takes a lot more "control" than I know how to pull off... can I ask how you did this?
