Getty strobes everything. Apples and Oranges. The average freelance photographer isn't doing to start laying out 15-20k to start putiing up stobes at high school or university basketball. The average Getty shooters are making between $100-500 per game, putting up strobes at NHL games still cost $1000-2000 per game or more depending on which arena, I assume the the NBA has a similar policy. These games I shot were in an NHL arena and were strobed by the NHL team photogapher who was using the team lights, that he didn't have to pay for. Unfortunately we don't all have the same privledge, so we do what we can.
