Interfit Umbrella accessories are used for soft light distribution and very slight shadows. Our umbrellas come in two types: the silver reflected umbrella and the optical white shoot-through umbrella. They do come in a range of styles including parabolic. Shoot-through umbrellas have small reflectivity due to the semi-transparency of the fabric and are used to reduce the intensiveness of a strobe light creating nice fill light, were reflected umbrellas have dense surface that is highly reflective.
