Could be a possible strange request.
Here at the court we're doing a production of Not I by Beckett.
It's basically a set of lips lit ranting for about 8 minutes and nothing else. And by nothing else I mean absolute complete blackout, not a single LED. It looks incredible but you need a complete and utter blackout.
I was hoping that I could create a macro that would turn all light (littlelites screen backlight etc) off.
Can you do this?
