Testing out processing procedures. I just discovered that the highlight tool (available in Lightroom 4 and 4.1) is magical. It gets rid of those ugly white centers, leaving nothing but color. Also, bringing up the blacks made the smoke disappear. The exposure on this one is a little longer than I like, making these fireworks more "spikey" but the colors are great. I had fun shooting them this year. I got an old fashioned wired off-camera trigger for my old Rebel Xt and it made it a lot more fun.
