The various types of umbrellas soften, broaden, and diminish the light output of any tungsten or flash light source. This is a 33" silver umbrella with black back. The silver interior cools the light considerably. It also does not soften light as much as white umbrellas.
This type of umbrella is great for product shots such as jewelry or when trying to eliminate the warmth of a subject. Umbrella size should be determined by the size of the subject, as well as the strength of the light supply being used. This size is ideally suited for small group shots.
