The White Studio Umbrella are designed to be used with any tungsten or flash light source, umbrellas will soften, amplify, and ease the light output to subject. Umbrellas with a white interior will soften and wane 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 lightbox. This umbrella is made of diffusive nylon fabric and easy to use in tight spaces. It has minimum light reduction.
Walls also make ideal Umbrella reflectors outdoors, reflecting sunlight back upon a subject and reducing shadows (and hence overall contrast) according to the color, size and proximity of the wall. A more readily available alternative is the portable, lightweight, collapsible reflector, commercially available in a range of sizes and colors, or improvised using a sheet of card stock or even a bed sheet. Stands may be erected to retain these reflectors, although it is often much more convenient and practical to have an assistant hold and manipulate them.
