Permission is sought, often after lengthy negotiation, to visit buildings closed to the public. Buildings that are fundamental to, if not somewhat discrete from, the everyday. Once granted, permission includes lists of restrictions on what can and cannot be photographed. Omissions habitually include: personnel, security devices, computer terminals, doors, and views from windows. Consequently, the resulting photographs are generally of the entrance hall floors; of such buildings as parliaments, government offices and the world headquarters of international banks.
