You have a nice shot there. Looks like you hand-held the shot with the camera steadied by a wall or a tree, is that what you did? You really need a tripod for this. Does the A620 have a connection for a remote release? If you have these things, try this: Mount the camera, lock the shutter open with the "bulb" setting using the remote shutter release, then cover the front of the lens with a piece of black cardboard or thick construction paper. When the fireworks go up, uncover the lens while the explosions occur, then cover it in between. Get about 4 or 5 good explosions, then close the shutter. It looks like this was a small, local display, so that's what you need to do to get enough explosions in. If this was a big production, you could get a decent amount of blasts with a 2-sec exposure.

Here's some fireworks I shot at our local 4th of July display in Valdese, NC. The control board for the fireworks wouldn't work, so they had to set them off by hand. A 20-minute show stretched out for one and a half hours. But using the technique above the pictures still looked pretty good. Each exposure was about 25 or 30 seconds, but with the lens covered most of the time the actual exposure was probably 4 or 5 seconds. These were shot on film, BTW, since I was dragged kicking and screaming into the digital age only a couple of years ago.

2-second exposures will no be long enough to get what your looking for. Somewher between 4-7 will be more like it depending on the colors. The one Gibbit shows has to many streaks for my taste. But it does look good.
