Actually it should probably read "Firestuff"? Just a few from the 4th this month.
Every time the 4th rolls around, there are a lot of questions, so I've put some info here to link to next year.
Exposure mode: Forget it! (Unless you want to go nuts & screw the shots up anyway.)
TRIPOD! Unless you want to rotate/move the cam during the burst as some people have tried.
Shutter speed is not relevant as a factor in the exposure. It only controls the amount (size) & number of bursts you capture. I used manual shutter with a remote cord & the cam on a tripod. Without the remote cord, you have two options:
You can squeeeeeze the shutter carefully & just live with the squiggles you'll get from cam movement, (which might add some interest to the shot) or...
Set the cam to about an 8 second shutter speed. Hold a black card in front of the lens, trip the shutter, wait a second for the cam to settle down & remove the card for the rest of the exposure. Put it back if you want to end the exposure early.
ISO 100. There's no reason to go higher unless you want to capture the background environment, & you can usually get that with a 4-8 sec exposure anyway. Remember that the fireworks will provide some lighting during that time to help out.
F-stop should be between f/8 & f/16. F/8 for the dimmer blue bursts, or f/16 to capture the detail in the bright white ones. How do you know what to use for the next burst coming up? I split the difference with f/11, shoot RAW, & adjust in processing.
Focus: Put the focus on "M", turn the lens to infinity & forget it. Shooting at a distance, the depth of focus at f/11 will pull everything into focus. If you're really picky about this, you can focus at the distance you think will be "right" & then tape the focus ring on the lens so it can't be accidentally changed. If you do this, put a piece of tape on the manual/auto switch too, so you don't accidentally change to auto while the focus ring is still taped!!!
Someone's going to ask what lens I used. The Kit lens at 18mm works well for these. This year I used a manual 20mm Nikkor 'cause the focus is manual & the f-stops are, too. It just made things easier for me.
Here's a Firebird & Fire flower to start with.
