This photo comes from my first attempt in capturing the colorful image of paints jumping/dancing on a balloon-covered speaker. Used a software called Multisine for the speaker to generate a frequency of 90Hz. The flash was triggered by Universal Photo Timer. This was taken on a dark room, so the exposure was done by the flash. Used only one flash, Sigma EF530 DG Super @ 1/32 power. PP - cropped, cleaned the background and sharpened.
