This is a subject close to my heart. The last 3 events in which I participated have had professional (to what extent I'm really not sure - could I have done the same job with a tripod and a £2000 camera?) photographers taking staggering amounts of images of each skater. They usually have a stand set up at the event and take orders for prints from the family and friends. Expensive orders. I'm talking the equivalent of $18 for one image.
