This is a segment — Wondercon in San Francisco — from the "Video Portraits" series
Project link is:

In this series of over 300 portraits, I ask a stranger if I can take photograph and instead I record video with my digital camera. Each person strikes a distinctive pose with a fixed smile and stares directly at the viewer, tapping into a universal experience of anticipation.

Subjects range from gay men at a pride parade, surfers in California, taxi drivers in Brazil, shoppers at a flea market and drunk people dressed in Santa outfits. Like conventional photographs, these serve as travel souvenirs. The videos grant duration to the photographic instant. The camera acts as a human eye, reflecting the complete shift to a documentation-based culture.
