I photographed a remarkabel phenomenon in the Ijen Crater in East Java, Indonesia. What you are seeing here is sulfur dioxide igniting from the hot lava in this very active volcanic basin. It was extremely difficult to record this in any kind of meaningful way because this isn't exactly what it looked like. Due to the blowing smoke and the long exposure in a moonless light, the blurred movement distorted the reality of what I was seeing. After braving a treacherous and steep rocky trail that descended 600 feet in the dark at 2am to get to the bottom of the crater, I used a combination of a long exposure and a powerful flashlight to obtain a reasonable exposure on the blue flames and the sulfur dioxide smoke. This is a four second exposure at f/4 with 1000 ISO.
