In response to another comment on this photo I would say that keeping the ISO down as low as possible would bring the glare down on firework shots. This also allows for less grain and a smoother effect. By doing this you are able to adjust the f stop and exposure to desired levels for multiple capture without over exposure. I am impressed with these folders Peter. Some very nice work. :)
Peter, I like the idea of the shots in this album, but I think the open aperture is doing you a disservice; it's allowing the fireworks to overwhelm your image sensor over the course of your exposure time.
Fireworks are very bright when they're exploding, and if you're going to take long exposures (which allows the beauty of the explosions to come out), then I really think you ought to consider stopping down the lens more. At least to f/8, but you might consider going as high as f/16.
That realization was a big eye-opener for me last year when I finally got my first fireworks pictures with which I was completely happy.
Narrow aperture was the counter-intuitive key to the whole affair. F/8 will halve the amount of light coming into your camera, and should allow you to capture some of the more subtle details like color, shape and trail which are being overwhelmed here by the sheer light of the explosion.
Let me know how it goes, eh?

No worries, thanks mate. It's a bit like taking photos of the moon. You'd think you'd need a longer exposure to get more light but there's too much light so you need a faster shutter speed to get a clear shot. I'll let you know how it goes.
