Additional to that, people who attempt to photograph or film fireworks tend to ruin the experience of just enjoying the fireworks for everyone else:
In my city there is an annual fair ground which has a firework show as feature. Just before the fireworks start, all caroussels and rides stop for the duration of the fireworks show and they switch off all the lights in order to get a good look of it. People who attempt to record the fireworks with their phone are blinding everyone else with their phone flashlights as they are looking for their peers in the crowd. Also, many photos of the event are taken with additional flash, because it is dark. Many of these photos will be deleted anyway, as they are out of focus or the picture has been shot right after the firework fades, because there is a delay in processing the picture. I involuntarily had to witness so many bad attempts of taking a photo, as I could see right into their phone displays.
