From the Eric Paré YouTube Channel:
About two years ago, we released "Signs of Light", the first video where we demonstrated how we use the tubes. I decided to go a bit further in this one by explaining the basic details to get you started with tube light-painting. This is a solid two minutes video with the important things you need to know to create images similar to ours. And as you’ll see, you don’t need much equipment: a plastic tube, a flashlight, a feather, a camera, a tripod and two radio remote triggers.
