I have taken fireworks photos every year for the last 3/4 years now, yet each year I forget to check what I did the year before to capture the light. This year I went full manual – ISO 100, aperture around 5 and bulb shutter with a release cable. Then I mostly guessed the exposure, watching fireworks spread in the sky until I though I had enough movement. Shutter times ranged from around two second, up to ten, all counted in my head.
The one thing I would strongly reccomend if you are trying to shoot fireworks, is to set the focus when the first firework goes off, then lock it to manual as you don’t want the camera trying to find focus instead of getting great images
The results weren’t bad:
The only problem is it is too hard to choose between the photos.
