Final answer:
Controlled lighting is commonly used to illuminate the perimeter of a facility. LED technology and automated lighting fixtures have expanded the capabilities and complexity of lighting design, requiring more preparation from the designer. Concealing light fixtures for realism and the type of lighting control system are also key considerations in theatrical lighting design.
Step-by-step explanation:
True or False: Controlled lighting is used to illuminate the perimeter of a facility? This statement is generally True, as controlled lighting is indeed used to enhance security and visibility around a facility's perimeter.
Lighting design in the theatrical context has evolved significantly with the advent of LED technology and automated lighting fixtures. These advancements allow for a wide range of adjustments in light parameters such as intensity, color, beam size, and even shape through gobos. This flexibility necessitates more preparation and decision-making from the lighting designer, as each cue in the technical rehearsal can include numerous choices that impact the overall design.
When a lighting designer opts to use architectural elements or stage drapery to conceal lighting fixtures, they are making a deliberate choice to maintain the illusion of a 'realistic' source of light. For example, to mimic the light from a table lamp on a large stage, additional key and fill lights may be used to amplify the source while staying hidden from the audience’s view. This technique serves to immerse the audience more deeply in the scene and keeps their focus on the actors and the narrative.
Finally, the type of lighting control system, be it a sophisticated computer-based board or a simpler analog one, is an important consideration for a lighting designer, as it dictates the complexity and flexibility of the lighting design execution.
