I think that windsurfing is a fabulous sport to photograph, especially if the windsurfers come close to land. It is a sport lavish in colour, and some of the moves are sumptuously rich!
All sports are lavish in some way or another. If you don't have windsurfers in sight, try finding a runner with a lavish shirt, or even just someone just walking in outlandish clothes.
What sport can you find today that catches your eye?
