I spent an evening in Hong Kong with my friends Pai and Lee. We walked randomly around the city doing some bar-hopping. It's very hilly there, so there are countless public escalators from point to point. I started a new technique where I set up the tripod on the escalator to do a long exposure to achieve this effect. It looks cool, but it's actually really hard to set up a tripod on steps that are moving… but I did achieve Level 4 Tripod Ninja when I got this photo.
