People in San Francisco love a reason to dress up. But Halloween gets especially intense, where the weekend transforms into a three-day romp of illusion, excitement and wild parties. I got my share of SF in freak show mode on Saturday night, so I decided to spend Halloween night with my camera, in my neighborhood, to document the people behind the masks. I set up a piece of white paper on a storefront, and voilà! I was able to capture some fun studio-esque shots!
