Fireworks are the same principle as photographing lightening depending on your distance from the firework and the desired affect.

For the following with a sparkler I used the same settings as the post I did previously about lightening (ISO to 100, WB to light bulb, and Aperature to 5.6), you can see the lightening post here.

The image I really wanted to play with is below, it’s my husband helping me out a little playing with a sparkler.

This image was only resized, no retouching, I’m not sure how you would go about retouching/fixing an image like this.

I used the same settings on this image:

As you can see this image has the same streaking as the I Love You image above. This is shown due to the settings on the camera and the amount of time the shutter is open. Both of these actions happened within feet of me. Had I altered the settings to cloudy, or a higher ISO there would have been far less streaks and would not have produced these affects.

Unfortunately I was busy playing with the fireworks and didn’t take many different types of shots so I do not currently have another other options to show you at the different settings.
