The concept of the invisible traces we leave behind (if we leave any at all, depending on who you're talking to) as we go about our lives has always fascinated me. I used to imagine people walking around the planet with a trail of every moment of their whole lives floating behind them like a cape. But it would be impossible to measure in moments because of the infinite nature of time and motion. So it became the question of what the compilation of all of our movements, measured by light and time, looks like. A couple of years ago I took a crack at it myself using long exposure photography. I took an inverse route and followed my moving subjects with a camera, capturing the motionless lights around them in a way that made the subjects look like they were stagnant, and that everything around them was moving.
