The large Umbrella Backpanel from Profoto is an optional accessory for Profoto's translucent umbrellas. The Backpanel's fabric is white on the inside and black on the outside and attaches to the umbrella with an integrated elastic band. A drawstring closes the panel's opening if desired. With the Backpanel attached there will be reduced light leakage backwards minimizing unwanted reflected light and producing more light coming through the umbrella and onto the subject. The Umbrella Backpanel virtually converts your translucent umbrella into a softbox.
