Light dancers

Great Smoky Mountains is known for its Synchronous Fireflies during each early summer. This year I spent 3 consecutive nights in early June staying in mountain area trying to capture this phenomenon. I was so lucky to witness a spectacular light show on an actual rainstorm night. I left my camera there for an 1.5 hour exposure. There were tens of thousands of fireflies dancing around using their light to paint the scene in front of me and I was the only audience of their light show. They are amazing artists of Mother Nature.
