I used a slow exposure, less than 1/15th of a second, to shoot these people waiting for a bus in front of an elegant illuminated advertisement. Since these people were travelers, I wanted to use an extended moment in time to express a feeling of transition and movement. The incongruity of the large scale woman in the ad contrasted against the smaller commuters was also fascinating. I had no idea that I would also pick up the red reflection in the glass over the ad – it provides a curtain lifting on a drama. The two men in this picture are faceless because they moved while the shutter was open – another bonus for me. The blurred faces of those men only add to this mysterious flow of travelers crossing paths on a Shanghai evening.
