This is an Impact Digital Flash Umbrella Mount Kit. It includes 2- Impact 32" White umbrellas with removable black backing. Umbrellas soften, broaden, and diminish the light output of any tungsten or flash light source. A white umbrella without a black backing may also be used as a makeshift softbox, although the use of the light will not be as efficient as with a light box.
Choosing umbrella size is determined by the size of the subject, and the strength of the light supply being used. Choosing an umbrella surface is as subjective as choosing a paint and brush. Each umbrella is perfect for a 1 person head shot, or 3x4 ft product setup.
Each of the two Impact brand umbrella brackets fit on top of almost any light stand, has different size stud adapters for various grip clamps, includes a cold shoe mount for your shoe-mount flash. It swivels, tilts, locks into place, and accepts almost any small to medium sized umbrella.
The Impact brand light stands are black, air-cushioned, and rise to a maximum height of 8' (2.4 m).
When using this kit with the Nikon SB-900/910 or Canon 600EX-RT, additional umbrella brackets which offer an "adjustable" shoe mount are required (see Impact #9101880).
