Yearbook staff using flashes during SV game

[Camron Rust]

Actually, the NBA and (bigtime) NCAA arenas are loaded with strobes mounted on the ceiling structure. The photographers have radio units which trigger the flash. If you watch a slow-motion replay, you will see single frames where everything in the picture has a much whiter look to it. This is when the photographer's fixed strobe fired.

Of course the difference is the the flash is much more diffused rather than a near point source.
