Lee,
Thank you.
This, and a couple of others that I have done recently, are actually double exposures.
I took one shot with my lens cap on, making a totally black picture. Using that as my background, I copy and paste, or layer another picture on top of it.
Then I go in and with a black eraser, erase any lingering background from the second picture. The result is something that is floating in space and almost three dimensional, don't you think?
