Focus On Lighting by Richard Cadena ETP04

Everything you always wanted to know about entertainment lighting but were afraid you would be too bored if you asked! Richard Cadena's concise work unravels the mechanics behind modern performance lighting and appeals to designers and technicians alike. Packed with clear, easy-to-read diagrams, the book provides excellent explanations behind the technology that is used on a daily basis in the lighting industry - often taken for granted, but rarely explained. The workings of dimmers and DMX transmission are clearly explained, along with Advanced Control Networks. For technicians there is an insight into power supplies, basic electrical theory and protection, and the mechanics of moving lights. For designers, there is an explanation of the scientific method of comparing brightness, which makes an excellent complement to the chapter on the Inverse Square Law, and a look into how dichroic filters work in comparison to traditional 'gels'. It provides the designer with an informed choice when selecting colour media. In total, the book shows the route that lighting technology has taken to where it is today, and an insight into what future technology is likely to bring the lighting industry.
