The Society of Professional Journalists has a great code of ethics on their web site. I bring this up because of a discussion thread on Cindy Green’s Videojournalist blog about the ethics of setting up a shot vs. creating a scene.
And finally don’t forget the Radio-Television News Directors Assoc. Code of Ethics.
Making ethical decisions in what we shoot, how we shooting and how we choose our topics is one of the most difficult things to teach and teach well. Hope these help.
