This photo was actually taken last year during a fireworks display with my Canon Rebel XSi camera and a starburst filter. I don't normally upload my photos, but this is one of my favorites that I've ever taken. It's sparkly and looks like a flower.
I cropped it, adjusted the colors and sharpness a little bit, and added the white border.
Edit: Oops, I meant starburst filter, not starburst lens.
There's definitely a difference between my Canon Rebel XSi and Sony Cybershot cameras. I get more detailed shots with the Canon, although the sony isn't too bad. I think the biggest thing you need is a camera that can shoot in a night/twilight mode.
