My dear friend Carla (and excellent photographer) is involved in roller derby. In Calgary, they just formed two teams and Carla asked me to grab some shots for their first match. It was held in the YWCA gym - the lighting was low and very flat - needed ISO 6400. None the less, was a family event with children in attendance - and the competition was interesting and not overly aggressive (although one lady did have a bad fall and could not continue). Background were a bit busy.
