Independence Day fireworks celebration at Centennial Park in Tinley Park, IL. How I did it;

1) Set camera (on tripod) to manual, bulb setting with lowest possible aperture setting.
2) Set lens to manual focus with image out of focus
3) When I saw a trail of light going up, I pressed my remote shutter.
4) I carefully adjusted the focus ring from out of focus to being focused (infinity on the focus ring).
5) Pressed the remote shutter again (8 seconds later).
