I set my tripod up to do multiple exposures and on the last and the longest a log went down the shoot and the flash went off for the photo you can purchase at the end of the ride. I was quite surprised when I looked at the screen to see how cool it was that their flashes light up the scene so perfectly. 5 shot HDR run through Photomatix. A little photoshop to remove my brothers large head from the bottom of the photo. Thanks Gary for getting in the way.
