Since you will most likely not have the money to hire contractors, art designers, and set coordinators to build a set for your digital video film you will probably be filming at real locations. If you are filming a news, home video, or documentary project then you will definitely be running around to actual locations to get footage. To make sure that you are able to shoot at a specific location, and that the owners or managers of that location will not take legal recourse against you for filming there, you should try to use a location release whenever possible. Be courteous and polite when asking for permission.
