I don't enjoy lugging a tripod around so these fireworks shots will look a bit different. They were shot handheld with the Pentax K5 and the 43 Ltd at f/4 1/20 ISO 12000 to 32000. The only post work done on these was to crop them. The star effect is striclty the characteristic of the 43 Ltd. No filters were used.
This was the view from my font yard last night around 9:45pm. The town park, where the fireworks are launched, is just down the road. It's not unusual for cities in Texas to conduct their fireworks displays on July 3.
