I've been doing some work with ESPN the past couple months, they're probably one of my favorite clients. They feature some of the best action sports photography including BMX, snowboarding, skateboarding, and of course surfing. This is John Maher from my last trip to Puerto Escondido, Mexico. It was shot with fisheye and an external flash on a cloudy morning. We both got tossed around during this session, but it was all in good fun. See my photo and others at this link:
