Nice images, what really caught my eye was your name image engineer. Seeing that my wife is an engineer, I am the creative one and she is the analitcal one, although as a software engineer who specializes in LABVIEW, I guess she is creative in her own world. Anyway I digress, The thing about fireworks is that it sorta depends on where your at to get really good ones.
If they shoot them low, relative to the cities ordences, shooting them one after the other and weather as a factor, humidity, causes the smoke to hang in the air, if you have too much smoke in the air the light from the fireworks makes a big white ball of smoke many times.

Is there anyway that you’ve found around this?

Thanks, nice work btw.
