Overview

The Westcott 4634 7-Foot Parabolic Umbrella is designed for photographers who need a large, soft light source without the bulk and cost of a comparably sized softbox. Its white interior diffuses and reflects light across a broad surface area, producing the kind of wraparound illumination that minimizes harsh shadows and flatters skin tones. When the removable black cover is attached, light is directed forward as a focused reflective source with less spill; remove the cover, and the white nylon canopy becomes a shoot-through diffuser that places the light source closer to your subject for an even softer effect.

Build quality centers on the 16-rib fiberglass framework, which offers significant advantages over metal-ribbed umbrellas — fiberglass flexes under stress rather than permanently bending or breaking, making it a practical choice for location shoots. The double-wall steel shaft adds rigidity where it matters most, keeping the umbrella securely mounted even when the large canopy catches air movement. The 7mm shaft tip is compatible with standard umbrella brackets, and the entire unit collapses down to under 45 inches for transport in the included storage case. At 2.5 pounds, it remains manageable to carry alongside the rest of your lighting kit.

Frequently Asked Questions

Yes. With the black cover removed, the white interior works as a shoot-through diffuser. With the black cover attached, it becomes a reflective bounce umbrella, giving you two lighting styles in one modifier.
The 7mm shaft tip fits standard umbrella brackets and most strobe/speedlight umbrella mounts. Verify your bracket accepts a 7mm shaft before purchasing.
Fiberglass ribs are more flexible and resistant to bending or snapping than traditional metal ribs, making this umbrella better suited for transport and outdoor use where wind is a concern.
It works with speedlites, studio strobes, continuous lights, and even as a natural light diffuser. However, a single speedlite may not fill the full 7-foot canopy evenly — a more powerful strobe or multiple speedlites will produce better results.
Yes, a travel and storage case is included for transport and protection.
