Lights can set the mood and affect the layout of a scene through the use of beam color, intensity, shape and position. Just as harmonic colors affect design parts, beam colors can lend a feeling of warmth or coolness to the scene. A beam's intensity, shape and position help to establish a specific part of the design as the focal point of the scene.
This lantern shares its name with the flat curtain found upstage which it is often used to light. Although it consists of only a reflector and a lamp, a cyclorama can paint beautiful colors on large areas. The shape of the reflector and the lamp determines the characteristic of the beam. An asymmetrical reflector is well-suited for lighting the cyclorama curtain. A symmetrical reflector produces a beam which is equally distributed above and below the horizontal axis of the lamp.
PAR (Parabolic Aluminized Reflector)
A PAR produces an intense, oval-shaped beam which can be rotated to cause the beam to appear tall or wide. Gels placed at the front of a PAR affect the beam's color. Unlike other lanterns, the beam is created in a sealed unit which contains the lamp, lens and a parabolic reflector. The shape of the reflector and the placement of the light filament affects the width of the beam. PARs are usually positioned above the stage or in the stage wings to create color washes.
Noted for the soft beam it creates, a Fresnel lantern is easily identified by the stepped concentric rings at its lens' surface. The beam's width is adjusted by changing the distance between the lamp and the lens. The intensity of the beam is brightest at the center of the lens and darkens toward its edges. Gels placed at the front of a Fresnel affect the beam's colors. Barn doors are used to shape the beam.
The beam produced by a pebble convex is not as soft as a Fresnel. However, it is softer than a profile's. The beam's width is adjustable like the Fresnel's, and barn doors are used to shape the beam. If a Plan0-Convex lens is associated with this lantern, the beam has a sharp edge. Gels placed at the front of a PAR affect the beam's color. The lens' exterior is pebbled.
There are two types of profiles: the fixed beam spot and the zoom spot. The superior optical characteristics of the former requires that beam's width be less variable. To improve optical quality, the latter is constructed to create a beam range of either 25 to 50 degrees or 18 to 32 degrees. Profile lanterns include shutters, gobo and iris slots to shape the beam. Interestingly, gobos must be inserted upside-down and backwards into the lantern in order to be correctly displayed. Gels placed at the front of a profile affect the beam's color.
Lanterns may be positioned above the stage, in the stage wings or in the house at the Tiny Pixel Theater. Those above the stage are called electrics. Booms and tabs are in the wings. Footlights are downstage. In the house, lanterns may be placed below an opera box, recessed into the walls on either side of the audience, hidden in the ceiling or clamped to the balcony railing. The B. Famous On Stage™ Magic application includes all of the positions seen below except footlights and booms.
