Tripod. Repeat. Tripod.
That was what I needed since longer shutter speed would be ideal for fireworks. Another thing I learned from other photography websites was that low ISO settings will produce better quality even though I thought darker environment usually means higher ISO settings.
Things to remember for the next fireworks: low ISO, set aperture between f/8 and f/16, use bulb setting and hold the shutter open for 5 to seconds, and use a tripod! And hopefully some richy-rich will tell me when he will be doing fireworks for his posh birthday bash.
