I tried a different trick with these -- INSTEAD of a long time exposure that lets you see embers fall to the ground, I left the camera open, then covered the lens with a black card (actually it was the back of a mousepad) except for very quick reveals when the shots went off.

These ARE in the order of shooting. However, they're also several fireworks per shot.

Hell with it. They turned out a lot better. Who cares what order.
