The acting areas were then keyed with a light source, which was placed to the downstage right side of each area. The Vari-l 0 (Figure 5), an open faced instrument much like a fresnel, was used. The Vari-l0 is also focusable and has rotatable four-leaf barndoors. Two set lights (Figure 6) were placed behind the window for night and day effects. These instruments, designed specifically for television, wash a drapery or backing wall with an even sheet of light. Their compact design is useful when space is limited. The plan was to wash evenly the whole acting area and then accent each area with a brighter source to highlight the actors regardless of the viewing angle. The instruments were kept to a minimum, and the dimensional effect was maintained. The position of the audience relative to the hanging position of the lights added another problem. The Multi-Broads were focused so that their reflectors would have been distracting to someone in the first row. Since they were lensless, the reflectors seemed to sparkle and created a problem. Spun glass placed in front of the instruments normally acts as a diffusion media and cuts about 50 percent of the light. Here it diffused the light rays so much that an additional problem of lighting the audience with this ambient light was added to the Figure 6 A set light. Designed specifically for television. it washes a drapery or backing wall with an even sheet of light. Figure 7 French Flags or cutters are attached to the yoke and positioned in front of the light to act as barndoors. ~ THEATER DESIGN AND TECHNOLOGY FEBRUARY.1971 23
