Water droplets

Sep 18, 2020

Bored during the 2020 pandemic, I tried my hand at water droplet photography. This is where you freeze action using a flash trying to catch two water droplets colliding. I captured some pretty good images before my solenoid valve got gummed up. I built the controller myself using an Arduino UNO and some transistors. This allowed me to precisely control the timing of the water droplets, the camera and the flash. The timing took a lot of experimentation which I adjusted through an interface to my laptop. A rough schematic of my setup is below.

Even before I got the timing correct, I managed to get some interesting images.

More to come after I clean the solenoid valve and set my rig back up.

CPA Reptile Macro

These photos were taken at a macro photography session at the Creative Photo Academy (associated with Paul's photo). The session was free but donations were accepted in support for breast cancer research. As you can see in the last few photos, these guys can be very friendly. I hope you enjoy my new friends.
