Key light: Godox AD360 with 1/4 CTO gel on the standard 8" reflector camera left. Manual bulb mode exposure with rear curtain sync set to underexpose the ambient about 1 - 2 stops below key.
Sarine is spinning LED poi that blinks and shifts colors rapidly. The LEDs light trails were left unfocused to create wilder patterns. The lens is brought back into focus at the end of the exposure right before the flash.
