reflective photograms

This past weekend in my normal scroll of the internet I happened upon a post by Philippe Dubost ( who has been posting shots using light painting with a pixel stick to write phrases in Montreal.

He has also posted a video tutorial on how to create the same effect using TouchDesigner.

So I set it up and my girlfriend and I spent some time playing around the apartment drawing with phones and flashlights. What became interesting was that since it was looking for the brightest spot, a reflection on a wall would also trigger the feeback/line to continue.

We than started painting our faces with light, with led to using the flash of a camera to imprint a silhouetted reflection.

I realized that doing this was the inverse of what photograms were. Rather creating exposures by blocking light, this process was producing similar effects by reflecting light.
