Vancouver Celebration of Light 2011 Fireworks – Spain
Day 2 of the Celebration of Light fireworks competition in Vancouver featured Spain on August 3, 2011. I love photographing fireworks and tried out the focus blur technique for some of the shots and got some cool effects! I put the camera on a tripod and set the shutter speed to bulb, the aperture to f/9.0 and used a remote control to trigger the camera.
I first focused the lens and noted the position of the focus ring, then unfocused the lens https://www.sihspune.org/propecia.php drastically. I waited until I saw some promising looking fireworks being launched, and triggered the shutter. I then focused the lens to the original position as the fireworks exploded. The technique creates wide lines of light that gradually narrow giving a flower-petal effect. Here are some examples from the Flickr focus blur group. The trickiest part is to avoid excessive movement when focusing the camera to prevent shaky lines. Timing is crucial and many of my shots didn't quite work out, but I did get a few nice shots!
