8 second exposure, I think, and I had to run on top of the slippery rocks with a pulled calf and then not move while holding the flash... I'm pretty soft, but I like the concept.. I'll find a better location when I have more time and maybe an assistant!
Thanks! I blended an orange exposure into the buildings because I love the way oranges and yellows play off of the blues... I can't wait to shoot this again right, to spend the time to find the right spot... It should really cool when I get it!
