The 43″ Apollo Deep Umbrella from Westcott has a deep design that creates a wide field of light with directional control making feathering easy. The umbrella’s 16 fiberglass ribs create a round light source while its soft white interior lowers contrast and fosters neutral color rendering. It mounts quickly to most strobes, constant lights or speedlights which can be positioned anywhere along the umbrella’s shaft to focus or de-focus the light to control contrast and coverage.
