Per SD Who Con policy:
Photography and videotaping of convention activities is permitted provided it does not cause a disruption, interfere with convention events, violate convention policies, or block the flow of traffic in and around the convention space. It is generally assumed that photography and videography will be occurring in public areas. However, if this becomes invasive, harassing, or causes discomfort, attendees have the right to ask the photographer(s) / videographer(s) to stop. Should any convention member, guest, or SD Who Convention staff member request that photographing or videotaping be discontinued, the request must be complied with immediately.
