Whether it be for a nation’s birthday, the dawn of a new year, or any other momentous occasion, fireworks have become a symbol of celebration used worldwide to provide entertainment in the form of explosive pyrotechnics. Characterized by sparks, smoke, and deafening cracks, fireworks inspire ooh’s and ah’s from mesmerized crowds, and often burn in the back of our eyelids long after the grand finale. But can we capture them on camera and still do justice to their grandeur?

The answer, of course, is yes – with the right techniques and equipment, anyone can capture this fascinating display of explosives as they illuminate and dissolve into the sky, and get really cool results.
There are several tricks to shooting fireworks that require practice and experimentation. As with most night photography, low ISO’s and slow shutter speeds are your friends, as are tripods, which will help you get a stable shot.
Previously we discussed Zoom blur and Zoom spinning techniques, which can also be applied when shooting fireworks. Today we would like to introduce the technique of Focus Blur.

Focus blur is a special trick that can turn a firework picture from decent to magical. This technique allows photographers to have part of their firework photograph in sharp focus, with other parts out of focus and blurred to lend a softer and puffier look to some shapes, while keeping other bursts perfectly clear.
1. Camera must be on tripod.
2. Set ISO to 100. ( you will need low iso not only by minimize noise from time exposure but also to allow longer shutter speed.
3. Set Shutter speed to 2 seconds as a starting point
4. Set F-stop somewhere f 5.6 , f8
5. Timing is very important and you have to experiment and get lucky as you never know what to expect from the next firework. Ideal time to press on the shutter is at the beginning of the burst.
(Test your exposure prior to moving to the next step)
6. Now the most crucial element: The focus blur.
Your Start Point (Soft Focus) for focusing will be on the other end of the scale (see image below)
Make sure to have the focus returned to sharp focus point quick enough before the end of exposure.
Basic Troubleshooting: If the shot come out overexposed. Reduce time or increase f-stop.
If everything looks blurry – Get to the Sharp Focus Point faster.
If everything is too sharp without the cool effect increase the rotation time.

To reverse the effect (as seen in the image above) start shooting at Sharp Point Focus and gradually turn your focusing ring towards the Soft Focus Spot.
