The patented Eclipse design is noted for the ability to provide cleaner, smoother highlights and catchlights compared to ordinary bounce umbrellas. All the bright metal exposed ribs of a normal umbrella construction are covered on the Eclipse umbrella. The EC45BC measures 45" along its curve. The flat-panel interior design is manufactured with a reflective color-neutral white material. A black cover attaches over the white panels to confine the light. This can be removed if desired, allowing the umbrella to be used as a shoot-through translucent diffuser.
