The extra-large 50" Pro DEEP Parabolic Umbrella from FotodioX is a white translucent shoot-through umbrella constructed for in-studio and on-location work. Sixteen fiberglass rods hold in place the umbrella's parabolic shape and combine with the inner nylon surface to produce a soft, even, professional light. The umbrella can be used with strobes and is heat resistant to use with continuous lights.
