In photography

Umbrellas with a reflective inside are used by photographers as a diffusion device when employing artificial lighting, and as a glare shield and shade, most often in portrait situations. Some umbrellas are shoot-through umbrellas, meaning the light goes through the umbrella and is diffused, rather than reflecting off the inside of the umbrella.
