HEY! I'm an A-Level Sound and Lighting designer. I'm now on my 15th Show and have come across an issue i've never needed to know before. The MD for the show (OLIVER!) Has requested a video relay between him and the stage. My question is 'how big does the screen need to be?' and 'where should i put it, not to disrupt the audience and not make the actors not look like they are looking at it????' HELP. Chris.
