This Westcott White Satin Umbrella with Removal Black Cover softens, broadens, and diminishes the light output of any tungsten or flash light source. Umbrellas with a white interior will soften and weaken light more than an umbrella with a silver lining. A white umbrella without a black backing may also be used as a makeshift softbox, although the use of the light will not be as efficient as with a lightbox.

Choosing umbrella size is determined by the size of the subject, and the strength of the light supply being used. Choosing an umbrella surface is as subjective as choosing a paint and brush.

Westcott umbrellas are measured tip to tip across the arch of the umbrella.

• Westcott umbrellas are rated safe for use with hot lights up to 1000 Watts.
