Softbox

A softbox is a type of lighting modifier used in photography and videography. It belongs to the group of devices designed to produce soft light. All the various soft light types create even and diffused light by transmitting light through some scattering material, or by reflecting light off a second surface to diffuse the light. One of the best known form of reflective source is the umbrella light, where the light from the bulb is "bounced" off the inside of a metalized umbrella to create an indirect "soft" light.

A softbox is an enclosure that surrounds a light source with reflective side and back panels and a diffusing material at the front to soften and spread the light.

The sides and back of the box are lined with a bright surface, an aluminized fabric surface or an aluminum foil, to act as an efficient reflector. In some commercially available models the diffuser is removable to allow the light to be used alone as a floodlight or with an umbrella reflector.

A softbox can be used with either flash or continuous light sources such as fluorescent lamps or "hot lights" such as quartz halogen bulbs or tungsten bulbs. If softbox lights are used with "hot" light sources, the photographer must be sure the softbox is heat rated for the wattage of the light to which it is attached in order to avoid fire hazard.
