Our local summer fireworks festival – 野洲川花火大会 – was held on July 25, 2015. Hundreds of people lined the riverbank along Yasugawa Sports Park to watch a 30-minute display of fireworks over the river. Many arrived in late afternoon, lined up to buy food and beverages, and enjoyed some entertainment before the fireworks began at 19:45.
Before the fireworks began I found a location upstream from the main event area, where I could record in peace away from the crowds. First I set up my tripod and tried different lenses with my camera, an Olympus OM-D E-M5 Mark II. I selected an Olympus M.Zuiko 17mm f1.8 lens for its focal length, wide aperture, and wonderful manual focus capability.
I wanted to capture high-quality audio, so I mounted an Audio-Technica BP4025 stereo microphone with a Baby Ball windscreen and a Windjammer and a Tascam DR-70 four-track audio recorder on my camera tripod. The camera was mounted on the Tascam recorder and received input from the recorder. I made a four-track dual stereo recording with the secondary tracks recorded at -12dB. This proved useful at first, when the mic gain was set to High. After a few minutes I set mic gain to Low with the recording level knobs at about 11:30. This worked well, although I had to stop recording in order to change mic gain because the Tascam recorder does not have a hardware switch for mic gain.
After minimal post processing with only trimming and overall level adjustment, I posted the finale (05:30) on SoundCloud:
The recording location can be seen on a map at radio aporee ::: maps – Yasugawa Fireworks.
Although I concentrated on video, I also took a few still photos. I tried about 2-8 seconds at various apertures with ISO 200. Some long exposures worked well, but timing can be tricky!
