I wish that I had taken this shot. But, I did not. I tried to do something like this, and it came out horribly.
I will try again soon. I used a tripod behind me in the middle. I just got a bogen super clamp and a little arm to work with, I have a cable release that helps to take these kinds of shots. But it really came out badly.
Here is the EXIF data for the emaple by Toni V, and for mine. I thought you would enjoy seeing me flub up one.
Thanks for looking
