Here is another shot from Rotorua, New Zealand. I had to pull over onto the side of the road and leap out of my car to grab this shot. The light literally was like this for less than 60 seconds. I just love how the sky looked like it was on fire. I took this on my Nikon D700 with 70-200mm f/2.8 lens at 1/1500sec and f/4.8.
