Broncolor Edge Mask for 60x100cm / 23.62x39.37" Softbox

An Edge Mask is an accessory for Softboxes. It is like an additional diffuser which you can easily mount on the front of the Softbox thanks to the Velcro. The inner part of the Edge Mask is a completely dark rectangle where no light is passing. The light only shines through the edges creating a frame of light. The purpose of the Edge Mask is to create a contour light around your subject. To achieve this nice effect, you place the Softbox with the Edge Mask exactly behind your subject.

The frame of light will illuminate the edge of your subject while the background stays black. To avoid having the frame of light in your image it is more convenient to use long lenses. The Edge Mask can be used for stills as well as for portraits. Depending on the subject you will have to choose the according size of the Softbox. As the shape of most sensors is a rectangle the Edge Masks only exist for rectangular Softboxes.
