To understand the importance of lighting, we must consider the 3 main functions lighting design may contribute towards a performance.
- Primary- To illuminate action
- Secondary- To enhance production with atmospheric effect
- Tertiary- Chronological, to suggest time/date of scene and definition of change.
Lighting design has radically changed the quality of production by expanding the possibilities, through enabling audience members to engage in performances easily through the use of tertiary lighting. The following choice of lanterns can all be attached to a Fly grid, Trusses or scaffolding. Consider your mood, what it is you are trying to light and space available.
Parcan: (Parabolic Aluminium Reflector) Simple bulb with a fixed beam angle to provide a narrow, powerful light.
Fresnel – Provides soft edged beam with variations, accessories include barn doors to shape the beam.
Profile: Gives a sharply defined image that can be altered by attached shutters, shaping the light beams appearance on stage. Controlled by an iris, creating a variable-diameter circular beam in which gobo’s can be added for further effects.
Flood: To provide large washes of light, equipped with gel frame to display colour onto a backdrop.
Control desks are used to distribute the light through channels, manually controlled desks use a number of faders to control each channel of light, crossfading controls are used to transfer between states. Computer controlled desks save each scene to memory and outputted when the controller requires.
Gels: Transparent coloured polycarbonate fixed in the direct light stream.
Gobos: Cut out metal patterns often used with gels, fixed into profile lanterns to control the shape of the light, creating logos, architecture or pattern.
