efficient, consistent light of uniform color temperature and evenness. The White model totally diffuses light over a large angle, producing a gentler light with lower overall contrast — especially suited for reducing reflections on the white walls of a studio. The Zebra, with alternating white and silver panels, increases light output 8/10-stop higher than the White umbrella, giving you more directional light and higher contrast with its slightly tighter angle. Metallic Silver increases light output by 1-6/10-stop compared to the White umbrella and its tighter angle results in higher contrast. Umbrella Diffusers can be mounted onto any umbrella to create varying degrees of silken light depending on which model is used.  (less)
