Microetchings are handmade lithographs that manipulate light on a microscopic scale to control the reflectivity of metallic surfaces in precise ways. These techniques were invented by Dr. Greg Dunn and his colleague Dr. Brian Edwards in order to change the way in which the viewer experiences a painting. Please note that these microetchings are designed to evolve based on the moving perspective of the viewer and are impossible to capture in still images.

If you are looking for the print version of this microetching, Pranayama: Breath of Fire, you will find it here.


Pranayama, controlling the mind through the breath, has been practiced around the world for thousands of years. With continued practice comes a growing awareness of prana, a subtle energy in the body whose movement can be controlled through breath.

This dynamically reflective gilded microetching depicts the movement of prana in the body as the viewer walks around it. When walking from left to right, the “inhale,” prana is withdrawn from the extremities, into the central channel, and upwards. When walking from right to left, the “exhale,” the prana moves back down the central channel and into the extremities. The microetching “breathes” as the viewer walks past it, providing a reminder to bring the mind back to a position of awareness.

Please watch the short film below, shot and produced by Will Drinker, to get a sense for what the microetching looks like. Please note that these effects are only present in the original 22K gilded microetchings, not in the print of this piece that you can find in the Print section. The print is a still photograph of the microetching.
