The diffusion umbrella cover is designed to work with Photoflex photographic umbrellas for converting into soft boxes with lots of light. This case fits over the front part of a reflective umbrella to cover it in a soft and light box. This works particularly well with silver interior umbrellas. The integral diffusion material transforms the brilliant light and transforms a reversible umbrella into a softer portrait light. Perfect for all types of photography where using a soft box.
