You get evenly scattered light thanks to the studio umbrella.
The larger the diameter of the umbrella, you get a larger light source, which minimizes the shadows of the photographed object. In combination with the correctly chosen diameter of the umbrella and flash, you can comfortably illuminate the whole figure. Silver reflective surface for brighter, sharper lighting, golden reflective surface for more pleasant warmer tones resembling soft light at sunrise or sunset, white diffuse umbrellas are used for perfectly diffused light and black prevents light, used where it is necessary to increase the contrast by shading residual lighting places of the scene.
Umbrellas are very versatile and can be used in virtually any holder for this type of accessory. The reflective surface is double-sided, choose which surface you want to use and simply place it on the structure of the umbrella.
