One of the displays from the last "After Glow" fireworks show from the 2013 Albuquerque International Balloon Festival. Without
a doubt, this fireworks show was the best I have ever witnessed in my life. The number of shells they put up was fantastic, and
then they started a different display / volley on the west end of the field and then switched back to the north end for the finale.
This is a single 3 second exposure with no special processing other than the large crop for comp.
Timing is everything when it comes to fireworks. It helps to have some luck as well.
