I’ve added a fireworks sub-gallery to the Night Gallery.
They were shot during on New Years Eve.

I set the camera on a tripod, aimed it where I thought the rocket would be, and set the focus to near-infinity. The lens was a 17-40mm at 17mm and the aperture was set to f8 or f9 and the ISO was 200. Then I set the exposure to bulb and covered the camera with a black garbage bag. I locked the shutter using a remote shutter release.
After the rocket was lit I removed the bag, and when it was done I replaced the bag. I did this several times, then unlocked the shutter when I was done. The result is a single shot with multiple exposures.
I hope you enjoy them.
