A scrim can be used indoors on a soundstage. For example, a set may be built on a soundstage to include both the interior and exterior of a wall with a window, thereby enabling characters inside to see characters on what appears to be a patio or walkway outside. The portion of the set that appears to be "outside" may have to be brightly lit to simulate sunlight. A scrim is then attached to a frame overhanging the entire "outdoor" portion of the set between the lighting and the actors, in order to diffuse the light so that it appears more natural when it hits the actors' faces.
