Light Them Up
Every indoor arena in the United States for the most part uses strobes for still pictures.
These lights are mainly used by the team's team photographer, typically for basketball and hockey. To the naked eye, fans and athletes probably don't notice the continual flashing on white light.
While there are some athletes that train to play with the flashes, including Michael Jordan, photographers often have images ruined by others photographers flashes. The term is literally called 'strobed' when one is exposed properly, but catches the flash of another, and it washes out the image.
However, I often try to use it to my advantage. I'll set a custom exposure and try to catch the strobe to help freeze the action with a slow shutter speed.
The results vary and it's a risk, but when it works, it's a nice mix to daily coverage.
