In cases where there are multiple sites, we pay our photographers to shoot one site fully (10 photos), as well as to shoot at least one cover photo per extra site up to 5 extra sites, which meets the minimum deliverable of 15 photos. Photographers are not required to shoot a site if it's currently occupied by other campers, and they might not be able to shoot multiple sites if they are far away from each other, requiring transportation.
If you have multiple sites, please work with your photographer to determine which ones are your highest priority (usually we recommend sites that are performing the best, and sites that don't already have good photos).
