what if he was a professional photographer for an architecture magazine but just was out and about to shoot some pictures of the stunts and volleyball for his own personal use and not to sell them...
asking if you're a pro is a misleading question b/c I can be a professional photographer for one thing but an enthusiast of another.
That's technically true, but I'm sure the OP was being asked if he was there on [Self-]assignment, not whether photography is his job or not. This kind of distinction is lost on most people who know little of the business of photography.
