so if Hammer tries to tell you they have a rule against taking pictures [except in the art section; I'm talking about presentations in the Billy wilder theatre] then you have a total legal right to do so for the sake of Journalism [professional or citizen journalism ] or for the sake of commenting upon, etc.... the only thing you can't do is video tape an entire show for personal profit to put online to make money ....but a few pictures or short video clips are completely legal !! Do not be bullied by Hammer Museum
[once again, please abid3 by their rules in the temporary art galleries, but be a citizen journalist with pictures & videos everywhere else, and don't let them liberal bully you lib-Bully ]
