Water droplets can offer endless photographic fun. This image shows what happens when two water droplets collide in mid-air. The process is simple, but timing is tricky.
First, one water droplet is let loose to fall into the cup, splashing back up in a center cone, and at just the moment when the cone peaks, a second falling droplet smashes into it. The camera also has to be precisely timed to capture the instant after impact.
For this, I use a special tool called the “Camera Axe”, good for remote triggering and timing your camera in countless ways. Without a trigger of some kind, a shot like this would be an exercise in frustration.
The water is coloured with food colouring. 🙂
