The GlareOne Umbrella Transparent 100cm is a handy and transparent flash umbrella suitable for photographers working with a studio flash set or continuous lights. This umbrella has a diameter of 100cm and can be used with almost any light source. Using this umbrella gives you a slightly harder light than, for example, with a softbox, but the light is softer than when you point the flash directly at the subject. This makes the GlareOne Umbrella ideal for preventing hard shadow lines and can be used when multiple light sources are needed. For example, you can use one or more umbrellas as fill flash to soften the light and reduce shadows.
