How to Shoot Psychedelic Spirograph Light Paintings

One of my favourite places to light paint is inside tunnels, waterways and other curved structures. These structures are perfect for creating spirograph light paintings. 


What are Spirographs?

Spirographs are geometric drawing instruments or toys used to create intricate mathematical curves or the variety technically known as hypotrochoids and epitrochoids. Developed by British engineer Denys Fisher in the early 60’s.
Spirographs consisted of two different sized plastic rings with gear teeth on the inside and outside of their circumferences. Once pinned to cardboard backing with a hole for a pen to extend through the other side they were spun around to make geometric shapes onto an underlying medium, often paper or cardboard. 



Spirograph Light Painting


Painting with light is no different from painting with a paintbrush or drawing on paper except the light is the paint and your sensor is the canvas. You move your instrument to create something physical.
Attaching LED lights to a bicycle wheel and moving it around a curved structure like a tunnel create spirograph light paintings. It sounds relatively simple but there is a lot of experimentation requiring patience and continuity to get the best results.
