When used with Halogen, flash/ strobe or even flourescent light sources, these professional photographic umbrellas will soften and diffuse the light output giving you an even, soft light. This type of light modifier has been used for years in portraiture, glamour, and product photography. With these professional umbrellas you no longer have to worry about hard shadows and highlights. Your work will benefit from the soft naturalistic light these umbrellas will produce. You can use these umbrellas with your key light, fill light or any accent light of your choice. The White/Black umbrella produces a soft, balanced light that is a little more subdued than the Silver/Black umbrella, making it the perfect choice for portrait photography, interviews and product work. The Silver/Black umbrella, because of its greater reflectivity, works well for glamour and product work where you want to emphasize the highlights.
