Follow Spots

Follow Spots are used in stage lighting in order to project an intense beam of light onto the stage. Often called spot lights, follow spots are usually controlled manually during live performances, by a follow spot operator whose job it is to follow the movements of performers on the stage. Follow spots are used in almost all stage productions and concerts, when it is necessary to highlight one or more individuals at specific times during the show. High-intensity discharge lamps are the preferred light source for most follow spots, although others can be used. To change the color of the spot light that is directed onto the stage, follow spots operators use something known as a color magazine, which is fitted to the follow spot and contains a number of different colored gels. The arrangement of follow spots varies according to the venue. Some venues have follow spots installed on the catwalk, or otherwise in the main control booth or special spot booths. During concerts, the follow spots are often mounted on trusses. These spot booths are installed in strategic places, to the sides, or at the rear of the stage, depending on the coverage requirements, and also other considerations, such as the architecture of the venue.
