4th of July is just around the corner and I need a bit of advice.
Below is a link to a shot I took last year with my T1i 50mm @1.4 no flash 1250 ISO.

The shot came out pretty good but very noisy and grainy; I will be shooting again this year with my 60D and hopefully with its higher ISO the noise will be reduced. Any advice would be appreciated as I have very limited experience with up and personal pyrotechnic photography.

Thanks in advance – the jpg is 3.3 meg so I provided the link; (REMOVED) rather than link direct.

The linked file isn't 3.3Mb it's 127Kb... that being said, I like it, and don't find it grainy... I wouldn't change anything...

Are you going to be shooting fires and stuff like in the picture? Or the fireworks? Tripod or no? Cable release?

High ISO for fireworks?

I will be shooting behind the scenes once again; it’s very chaotic as the individuals firing each shot have to choreograph by time/count as we cannot hear the music due to the concussion. Due to all the movement I don’t use a tripod or trigger.

I both act as both photographer and shoot the 4” mortars, and the finale. My wife will be shooting the event from the spectators section with my T1i on a tripod so we will have both cause and effect; hoping I can get some better behind the scenes this year.

I set up on a tripod using my remote shutter switch, Manual (Bulb) mode. F/9 to f/11, I've even gone smaller, ISO 100, and just hold the shutter open for as long as I feel for however many fireworks are going off at the moment. Most of mine are anywhere from 3 to 5 second exposures.

That is all well and good from the crowd’s perspective; looking at the photo you can see that 3-sec exposure would have been nothing but a red-blur.

Look at it another way; a 6” fuse burns in about 0.2 sec, you have enough time to position the flare at the base of the fuse and rotate your face/body away from the concussion as it ignites. (you can feel the concussion of the 8” mortars way back in the crowd, imagine how powerful that is 24” away.)
To capture the shot I linked you must time the depression of your shutter within that 0.2 sec, high ISO and fast shutter speed with aperture wide open to grab as much light in that spit second as possible. Firework photography I understand; long exposure, ISO 100 with f11-f13, focus set to infinity. Up close and personal is a bit different .

High ISO is there for a reason and this is one of those times, no use trying to fight it. Besides, the shot in the OP looks fine to me (Although I'm seeing an EXIF of f2.8, not f1.4).

The technique used here is to choose a shutter speed and let the camera figure out everything else. There's no reason to worry about background because it's going to be black, regardless of everything else.

First, did you see the Fireworks "Sticky" above this thread?

From their support:

Before uploading your images to your Photobucket account, choose either a
display or file size that is equal to or larger than that of your images. You
can do this by clicking on the 'Uploading Options' link in your upload panel
and then on the radio button next to your preferred size. If an option is
grayed out, this means the option is not available for your Photobucket
account type. Selecting a size larger than your images will prevent further
resizing upon upload and help expedite the upload process. To make the changes
permanent, you must upload at least one image from the upload panel. This is
important for Pro users using FTP or anyone using the Windows XP Publisher. If
you choose to use the file size options, the file size of the original image
will take precedence over the the display size and any display size is
accepted as long as the file size is less than your choice in the 'Uploading
Options'.

I did read the Fireword sticky; it does not address how to shoot the launch, and that was the advice I was seeking. I believe I have a good handle on it, and hopefully will have better performance with the 60D at 3200 ISO. I may set up the camera on a tripod with wireless remote to see if I can get rid of some camera shake too.

The photobucket is my fault

Here is a shot of the grand finale before we loaded them

Even though you didn't say that, the exposure advice should be pretty accurate. I'd start at about 1-3 seconds @ f/16, ISO 100 & work from there, but you might want a shorter shutter speed to avoid blowing out the fire. I also suggest that you set your focus while there's some light to see with, tape the lens, & turn AF off.
