Continuing from my last post, Lens blur technique isn't difficult but it also is not easy. You can try practicing on street lights or fairy lights. The trick is to use a steady hand and move the focus ring from infinite all the way to the end, you can also start at the close focal point and go to infinite.

To get a great shot this must be done in the time frame that the exposure is set to and avoid any shake from this movement.

I my self am still getting used to this technique and get better with every attempt.

With this you can get many interesting shots out side of normal firework photography.
