This is the Elinchrom Barndoor Set for 21 cm Standard Reflector which can be used to control where light falls on your scene. The size of the light spot can be determined by the opening of the leaves, and the distance of the light from the subject. Rotating the barndoor set will offer more control over where light is placed and a 4-leaf barndoor provides more light control than a 2-leaf barndoor set.
