I had lots of fun making this picture. First i wanted to see a light dropping on a candle, second i made the candle a lucifer, but that did not work well.
Finally i blew the candle out and tried to get the shot like the flashlight blows out the candle to make clear that two kinds of light are actually real different. They attract to each other which can be seen in the flowing lines when different lights come together, but when one of the lights is harder the other becomes almost unvisible.
