Tips to shoot fireworks

1. Use a Tripod – It will make a world of a difference.
2. Use Low ISO – The low ISO will make sure the everything is not over exposed
3. High F/Stop – The High F/Stop will help keep things sharp, and will control the exposure of the crowd.
4. Focus on distant object, manually if easily done
5. Long exposure time, try 2 to 8 seconds – The long Exposure with get you nice fireworks trails. With a long exposure, you can start the exposure when the previous fireworks fizzle out, and before the next one begins.
6 . A medium to wide angle lens works really well.
