A dash of science meets 100% art. Absolutely love this “dancing colors” series of images from Swiss photographer Fabian Oefner.
The basic idea behind it is to bridge the acoustical and the visual world—if only for a fraction of a second.
Fabian Oefner places normal salt, colored with pigments, on a thin foil of plastic, which is wrapped on top of a speaker. As soon as the speaker receives a sound, the plastic foil starts to vibrate, forming these strange figures.
In order to capture the specific moment, where the pigments are lifted into the air, Oefner attached a microphone to the speaker, which is again connected to the flash system. As soon as the speaker emits a sound, the microphone picks it up and sends a signal to the flashes to trigger them.
