The subject for the night was “Psychedelic CD Water Droplet Patterns” and we started the evening a video tutorial on how to go about this.
We then gave it a shot! The idea is to put a CD onto a dark background and then place water droplets onto the CD. Set the camera for 10-20 seconds shutter and shine a torch light at the CD, moving it around various angles. The results are quite spectacular as you can see below from the images that Fran kindly sent in.
