I'm often asked how I take these pictures and what technique I use.
It's actually quite simple. You take something that glows,
swing it through the air and take a photo. However, with a long exposure,
about five to ten seconds. That's all.
I found the first LED strips in an electronics shop at the beginning of the 1910s.
Glued to a rail, soldered to a long cable and a battery box
at the other end of the cable. That was my introduction to using LED technology.
It wasn't ideal, because the cables were a nuisance and were visible in the picture despite movement
during the shot.
The next generation of my LED sticks had the batteries integrated into the sticks.
There was nothing ready-made to buy back then. Therefore, each stick is a self-made unique item.
The construction was not exactly easy, because the batteries also have to be charged.
Normal batteries were also unsuitable, because they only had 1.5 volts.
The LEDs needed 12 volts, however. The new lithium-ion batteries were the solution.
These are now installed in almost all portable electronic devices.
However, handling these batteries is not as easy as with conventional batteries.
In the third generation of LED sticks, I also built remote-controlled electronics
for selecting the color and brightness of the LEDs.
The fourth generation was then a little more compact.
A fifth generation is not planned, as these sticks are now available ready-made.
They can also be programmed, for example to write text with light.
But I find that less interesting and less useful for my style of photography.
All photos shown here contain no image manipulation.
Artificial intelligence was never involved either.
All images are as they come out of the camera.
