Nerissa and protestors. Dolores Park, S.F. April 20, 2002 Anti-War Protest. Nerissa is the woman with her fist aloft and a sticker on her face at center. She's in my graduate program at Cal and I ran ahead of the march and quickly pointed backwards to get this shot. One of the qualities of the N90S is that it has a very fast auto-focus system. It also helped that it was bright daylight, and therefore, shutter speed was probably close to maxed out.
