Water Drop Photography

  • Water Drop Photography

Taking a shot of an event that lasts a fraction of a second can involve a lot of trial and error, and it can be frustrating too especially if you're not getting results you've hoped for. Water drop photography is one of these subjects that a lot of photographers may want to try, but not know how to go about it.

In order to get repeatable successful shots, you have to be able to control as many factors as possible. The timing of your camera's shutter, the timing of the flash, and the timing and size of the water drop. The equipment I use is built using an Arduino Uno, a small electronics project board that can be used to control objects in the physical and digital world. Connected to the board is a water valve to deliver a droplet of water, an infrared light to trigger the camera's shutter, and a flash trigger to fire the flash at the right moment. There's a couple of buttons and a display that allow me to adjust the timings, but once it's set up, I just press a button and a couple of seconds later I have a shot.

Everything is timed to millisecond accuracy - this allows me to vary the height of the water valve to get a bigger or smaller splash, and varying the point at which the flash fires will determine if I capture the start, middle or the end of the splash.
