Scrims both reflect and transmit light. 1  This means that if a light from a front-of-house position is shone at a scrim, then both the scrim and everything behind it will be lit. This can lead to a variety of interesting effects: 1  A scrim will appear entirely opaque if everything behind it is unlit and the scrim itself is grazed by light from the sides or from above. 2  A scrim will appear nearly transparent if a scene behind it is lit, but there is no light on the scrim.
