I've worked in this shot for weeks! At beginning, I was planning to exposure this in 3 hours. But my batteries died in the end. Then I tried 2 hours, but the lights and colors didn't work it out as I imagined, so it failed again. At last, I tried to find the right time to shot....The time between all these lights on and off! And yes~it works~
I hope you will like this my friends~:))
