Not all convertible umbrellas are equal! PROMASTER SystemPRO convertible umbrellas have two layers. The outer cloth is made of black material coated with a highly reflective silver surface. The inner cloth is white diffuser material.
The SytemPro convertible umbrella can either be used as a reflective umbrella or the black/silver cloth can be unclipped and the umbrella can be used in the shoot through mode allowing great versatility.
SystemPro Convertible Umbrellas come in both a 30" and a 45" model.
