Very beautiful picture. Excellent sharpness and colours. Was it difficult to get that freeze effect? I mean, due to the darkness the exposure must have been quiet long...
Impressive work and a very fulfilling and interesting note.
Thanks for sharing!

Nice firework picture. The exposure is just perfect! The sharpness and the colors are excellent. Not easy shot but very well done.

Good Shot Vic.
I find it amazing how you captured the explosion of the fireworks, but no "flash" from when it exploded? How'd you manage that?
