this is my first entry on 500px. what a great site, i love the design and simplicity of it!
i have created a new series called "dancing colors". the idea of the series is to build a bridge between the acoustical and the visual world. the sculptures, you see on the images exist only for a fraction of a second. they consist of normal salt, colored with pigments. the salt is placed 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, i 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. since i took the images in a completely darkened room, i can just leave the shutter open for a few seconds, only the event illuminated by the triggered flashes is captured.
the shooting is very time-consuming since one has to clean the whole setup after every shot. it`s also a very messy business, everybody, who has ever worked with color pigments knows what i mean :-)
