One 17 minute exposure at multiple apertures. Using a manual lens on my t1i at ISO 100, I painted at f/4, 5.6, and 16.
f/4 for the purple tree lighting on the sides.
f/5.6 for the other gelled lighting, green el wire, and rainbow schoon stick path.
f/16 for the fountain spin and sparkler run.
I tried the light cube in the middle of the spin which was a bad idea although it doesn't show up much. I also wish I had lit the right side a little more. I do like how star trails come out when you do the f-stop shuffle though.
After 30 minutes of test frames and a 17 minute shot, I wasn't up for a redo. This would have gone so much easier and quicker if I had someone helping me out.
I'm off on a golf trip with my Dad, Uncle, and Cousins until Sunday. Enjoy your weekend!
