Super moon: super picture!!! Greetings from Brazil!
I set up my camera on a tripod and had someone hold down the shutter as I jumped off the rock. I then used Photoshop to combine all the pictures together on different layers and then merged just the parts of the images that had me at the different points. All this is fairly easy to do since I used a tripod and the background remained almost identical from shot to shot. I actually had two more images towards the top of the jump that I didn't use since it made it kind of cluttered.
Hope that makes sense. :)
