This medium Umbrella Diffuser from Profoto pulls over the front of a white or silver umbrella to turn it into a softbox. It creates a softer, more diffuse light. The diffuser will also reduce the output of your light by approximately 1.5 stops. This model is compatible with the medium shallow and deep White and Silver Umbrellas.
