To create these images, I used a flat dish filled with water placed it in front of a white surface. For timing the exact moment of the impact of the water droplets, I used a syringe which was fixed above a self-built light barrier made out of a laserpointer and a photodiode which I had lying around. This light barrier was connected to an Arduino microcontroller which was used to finally trigger an external flash with a delay of a few hundred milliseconds.
After completing and testing the setup, I exposed each image with my Olympus OM-4-Ti in bulb mode while the room was completely dark. The flash was pointed to the wall behind the water filled dish and then triggered by the water drop going through the light barrier, effectively capturing and ‘freezing’ the splashes mid-air.
