Reflectors may also be used as a means of increasing the size of the main light source, which may (or may not) retain a direct path to the scene. By positioning a board reflector close to a light source, its effective size can be increased by "bouncing" the light off it.[3] A very common example of this technique is the traditional umbrella reflector, invented by George Larson, typically having a gold, silver or matte white interior onto which a lamp fitted with a circular reflector is projected, providing a broad, soft illumination. The lamp faces away from the scene to be photographed, allowing only reflected light to be thrown forward.
