One of the major issues that lighting designers constantly struggle with is how to represent the changing character of a lit environment. At any given moment, light can be described in terms of its spectral distribution, colour rendering, colour temperature, illumination and luminance measurement scales. But there is no standard mark-up language or established system to describe how the lit character of a space changes over time, to enable lighting concepts to be documented, information disseminated and a lit environment to be evaluated. Without a system to record and analyse light, it becomes difficult to provide a qualitative and quantitative assessment.

Its greatest impact, however, is in the horror genre. From the earliest days of German impressionist films such as Robert Wiene’s The Cabinet of Doctor Caligari (1919) and Friedrich Wilhelm Murnau’s Nosferatu (1921) to Ridley Scott’s Alien (1979) and Donahue, Leonard and William’s Blair Witch Project (2002), the light – or in many cases the lack of it – has been integral to creating the fear factor. In horror movies light is commonly used to reveal or conceal the object of horror by employing various lighting techniques:
