Profoto Backpanel for Umbrella Translucent M acts like a shower cap with an elastic band. Place it over your Translucent Umbrella to turn it into a softbox. The backpanel is a white fabric on the inside and black on the outside. By using the backpanel you will have no scattering of light from behind that, bouncing around, could affect the quality of the lighting on your subject. More light will also pass through the umbrella and hit the subject. For this reason it is an excellent tool when you have limited power on your flash unit. The Profoto Backpanel for Umbrella Translucent is made of high quality heat resistant materials and comes in a soft case with label.
