@Ling: Thanks sis. Can't wait for your fireworks pictures! A tip from Eddie - get ND filters which will help cut down over exposure - I did not use any filter for my pictures though. Set shutter to bulb mode or slower shutter speed. Know where to aim and when to anticipate the burst (many of my pictures had their fireworks cut off or I caught the tail-end of the burst - a pity). And tripod of course!
