on lighting designers

so I was thinking...

 good Lighting designers are kind of like the actors you never see on stage. you could do a show without a set. you could do a show without costumes. but if you do a show without light...
light motivates, sets the tone and the mood and controls the focus.

and much like a performance from an actor, the light on stage will never be the same twice. and once its done. it could never be recreated exactly the same.
