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 ECP60 measures 60" over its curve. The flat-panel interior design is manufactured with a reflective color-neutral white material. The PLUS cover is a removable black-with-bonded-silver lining that's designed to reflect an extra stop of light. This increase in bounced soft-light allows placement slightly farther from your subject. The cover can be removed if desired, allowing the umbrella to be used as a shoot-through translucent diffuser.
