Follow-spots are one of the most familiar dynamic tools for lighting a performance. which has been used in the theatre since the first half of the 19th century in the form of limelights amd arclights. The follow-spot has a particularly intense beam which stands out against any other lighting on the stage. As the brilliant beam moves from one place to another, it focuses the attention of the audience. Follow-spots are conventionally used to highlight leading dancers, singers and actors.  It has become so much of a convention in lighting of certain genres that its absence adversely effects the star performers in opera, ballet, conventional musicals and rock concerts.

The follow-spot can be used to focus attention in two different manners or styles:

Hard-edge focus: The beam of light encircles the actor   in a clear-cut round beam of blazing   light.		Soft-edge focus: The soft beam discretely focuses attention on the lead character.Soft-edged focus is often used to accent rather than to isolate, in which case the follow-spot will be only slightly more intense than the general   level of lighting on the stage.

In small auditoriums (up to 250 seats), an ordinary 2000W profile-spot with an iris shutter can be successfully used
as a follow-spot.

Followspots need special follow-spot positions which will allow space for their large size and for the follow-spots operators. These can be special follow-spots booths at the back of the highest gallery, light bridges in the auditorium ceiling, or on-stage portal bridge and side galleries.
