This pattern could create an image, like a city skyline, or it could simply add some texture to the light. By placing the gobo in a holder in front of a light source, the light will cast a pattern on the stage. Gobo: A gobo, also called a pattern, is a thin metal disc with a pattern cut out, like a stencil.By sliding different gels into the color frame on a light, you can use the same light to cast many different colors. Gels consist of clear sheets with a translucent colored sheet of plastic in the middle. Gel: A gel, also called a color filter, is what lighting professionals use to change the color of a beam of light.By moving the shutters, you can manipulate the shape of the light and block certain areas. Shutters: Shutters are similar to barndoors, but they are built into ellipsoidal lighting fixtures.The barndoors shape the light and create a harder edge where the light stops so the beam won’t illuminate areas you would prefer to remain dark. Barndoors: Barndoors are sets of either two or four metal flaps that affix to the front of a stage light to cast a widespread, soft beam of light.Lighting engineers can use diffusion material, which is like a colorless gel, to soften the light. A diffused light is the opposite of an intense beam with hard edges. ![]()
