Here are a couple I took last year. This was my first attempt. With the brightness of the fireworks, you need to think in terms of daylight shooting. Tripod and remote are a must, manual focus on city, manual priority f/8 or f/11 set to bulb, ISO 100. push remote when firework starts to explode and release when it is finishing. Too bad I had my crap kit lens EF-S 18-55 last year. I have L glass now.
