Javid discusses, with Webster and Ron, the technological evolution of controls, from the ancient Greeks using mirrors to control light for the stage, to “old telephone” style patching, to digital controls. If you haven’t guessed, Javid, like many of you, comes from a theatrical background. Wait till you hear how he lit a production of “The Crucible.” You’ll wish you’d seen it. Javid Butler is a lighting designer and energy engineer who holds LC, CEM, and CMVP certifications. He has contributed to the development of many lighting standards including RDM and sACN, and chaired the task group for E1.27 DMX512 cabling standards.
