Water drop photography is something that sounds ridiculously easy to do however, in practice, isn’t as simple as you would think. It involves dropping liquid into a container of more liquid and photographing it at the point where the droplet hits the bowl of liquid.
This is something I recently tried and although I managed to get a few good results they were still far from what I had hoped to achieve. I set the camera up on a tripod with a fast shutter speed and connected it to a remote control so I could control both the drops and the camera with a bit more accuracy.
Basically what I did was squeeze a drop of milk I had dyed red from a bottle and then took a photo at the moment the drop hit the water which was located about a foot below.At the top of this article is an example of what I came up with
As you can see, it wasn’t exactly fantastic.
So, how do you do it with almost guaranteed great results each time without spending a fortune on a rig? Remember Dave Hunt, the guy that produced the home-made Macro Rail I wrote about not so long ago?
Well he’s created a rig using a Raspberry Pi, some electrical know-how and some off-the-shelf items from his local DIY store that allows him to control the release of the water drop and then times it almost perfectly for the photo. Here’s an example of what Hunt can do…spot the difference!?
Using the Raspberry PI’s GPIO connected to both the camera and a solenoid valve, he was able to start the water droplets and trigger the camera. I for one am looking forward to Dave’s next adventure with his Raspberry PI!
