Hi everyone.  I'm still a relatively "new" race planner, although I've been event planning for 15+ years.  We've been approached by a photographer to be an "official photographer" for our event; in years past, we've taken candid photos of the event as well as award ceremony and provided copies of those photos to our winners at no charge.  Do you find this a normal practice--to have an "official photographer"?  I'm concerned because in order to contract with him, he wants our race list; our race is part of a parks and recreation department's overall program schedule, and our policy is not to sell or give out our roster info.  Are racers accustomed to getting these types of promotions after races--"come see your race photos at xyz website!"  Your help is appreciated.
