The Gary Fong Lightsphere Universal Inverted Dome Flash Diffusion Basic Kit is based on the large round soft & flexible Lightsphere diffuser that slips over the front of any standard shoe mount flash unit. The inside of the Lightsphere is completely textured to make the light dispersion even softer than it would be otherwise. As a result the material is more translucent keeping the unit from losing a lot of light while actually increasing the diffusion & softness of light. An opaque color has been added to the inside of the Cloud version & this frosted version creates an even softer effect which makes it absolutely ideal for close-ups portraits & event photography. The included inverted dome means that you can softly diffuse direct light with a large soft source without creating flare on the front of your lens. The included Amber Dome warms the light from your electronic flash for shooting outdoors at dusk or early morning open shade interiors with tungsten lighting & sunsets with the sun behind the subject. The included Chrome Dome seriously increases the light output while still keeping the diffusion properties of your flash unit. You will have up to double the power & efficiency but the look will be identical.
