It was taken in Wellington, New Zealand.
And yeah, that's the only one I've combined because the fireworks are actually much further out in the harbour, so anyone who knows where the fireworks are would know that it's not an actual shot from the day. I find that the shorter shutter speed still works pretty well during the finale because they're shooting them off so fast. I'll have a dig through some of the old shots and see if I have any from the finales that turned out. There must be some somewhere
If I find any I'll post with the EXIF etc.
