Belgian photographer fotoopa (“photo grandpa” in Dutch) shoots ultra-high speed photographs with laser rigs he builds himself.
To capture insets in flight, his rig detects the insects using two crossed laser beams. This causes a “superfast electro magnet” to trigger the shutter, which opens and closes in less than 5 milliseconds. Shooting at f/22 and ISO 100, he uses 2 or 3 external flashes at minimum power to obtain sufficient light at so short a shutter speed.
“I’m retired, and work inside in the winter making high-speed pictures of water figures. In the springtime and summer I’m outside to capturing insects in-flight. I have a mechanics (15 years experience) and electronics (26 years) background, but photography was always my hobby.”
